Thermistors is sintered in high-temperature (1200 °C to 1500 °C), and manufactured in various shapes. It’s comprised of 2 to 4 kinds of metal oxides: iron, nickel, cobalt, manganese and copper. Features Recommended Applications ● ● Temperature Coefficient of Resistance is negative, and it’s extremely large (–2.8 to –5.1 [%/°C]). ● Various shapes, especially co mpact size components are available. ● Selection of resistance vale is comparatively free, it’s available from several tens Ω to several hundred kΩ. For temperature measurement or temperature detection : Thermometer, temperature controller ● For temperature compensation : Transistor, transistor circuit, quarts oscillation circuit, and measuring instruments Physical Characteristics of NTC Thermistors Thermistor is a resistor sensitive to temperature that is utilizing the characteristic of metal oxide semiconductor having large temperature coefficient. And its temperature dependency of resistance value is indicated by the following equation : R=R0 exp [ ( B 1 T 1 T0 )] Fig. 1 1000 100 .....................................(1) 10 RT/R25 T0 : Standard Temperature 298.15 K(25 °C) R0 : Resistance at T0 [K] B : Thermistor Constant [K] Temperature coefficient (a) in general meaning is indicated as follows : 1 2000 3000 400 0 500 0 60 00 0.1 B .................................................................... (2) 2 T 0.01 Since the change by temperature is considerably large, a is not appropriate as a constant. Therefore, B value (constant) is generally used as a coefficient of thermistors. 0.001 a= B=1000 –40 –20 0 20 40 60 T (˚C) 80 100 120 140 Major Characteristics of NTC Thermistors The relation between resistance and temperature of a thermistor is linear as shown in Fig. 2. The resistance value is shown in vertical direction in a logarithmic scale and reciprocal of absolute temperature (adding 273.15 to centigrade) is shown in horizontal direction. The B value (constant) determines the gradient of these straight lines. The B value (constant) is calculated by using following equation. knR1 – knR2 1 1 T1 T2 700 =4 0 B 25/5 100000 10000 ....................................................... (3) R1: Resistance at T1 K R2: Resistance at T2 K When you calculate this equation, you’ll find that B value is not exactly constant. The resistance is expressed by the following equation : R = AT–C exp D/T ............................................................. (4) In (4), C is a small positive or negative constant and quite negligible except for use in precision temperature-measuring device, therefore, the B value can be considered as constant number. In Fig. 1, the relation between the resistance ratio RT/R25 (R25 : Resistance at 25 °C, RT : Resistance at T °C) and B Value is shown with T °C, in the horizontal direction. 500 44005 = 00= /55 □ BB2255/ 0 □ □ 104 4 25 EV EP473 0 0= J 0 5 T RTJ 5/ 2 R B E E □ 5 03 343 R1 5= E 0 25/8 J B T 0 A 5 0 ER 3□ =4 G10 /50 5 E 2 0 B J □ ERT 02 T1 E TJ0 ER 00 =28 B 25/50 □ 1 A10 J0E ERT 1000000 R (Ω) B= Fig. 2 10000000 1000 100 10 1 2.4 125 2.9 85 3.4 1 (×10 –3K–1) T 50 25 T (˚C) 3.9 0 –20 4.4 –40 Design and specifications are each subject to change without notice.

When subjected to severe electrical, environmental, and/or mechanical stress beyond the specifications, as noted in the Ratings and Specified Conditions section, the Thermistors’ performance may be degraded, or become failure mode, such as short circuit mode and open-circuit mode. If you use under the condition of short-circuit, heat generation of thermistors will occur by running large current due to application of voltage. There are possibilities of smoke emission, substrate burn-out, and, in the worst case, fire. For products which require higher safety levels, please carefully consider how a single malfunction can affect your product. In order to ensure the safety in the case of a single malfunction, please design products with fail-safe, such as setting up protecting circuits, etc. ● For the following applications and conditions, please contact us for product of special specification not found in this document. · When your application may have difficulty complying with the safety or handling precautions specified below. · High-quality and high-reliability required devices that have possibility of causing hazardous conditions, such as death or injury (regardless of directly or indirectly), due to failure or malfunction of the product. 1 Aircraft and Aerospace Equipment (artificial satellite, rocket, etc.) 2 Submarine Equipment (submarine repeating equipment, etc.) 3 Transportation Equipment (motor vehicles, airplanes, trains, ship, traffic signal controllers, etc.) 4 Power Generation Control Equipment (atomic power, hydroelectric power, thermal power plant control system, etc.) 5 Medical Equipment (life-support equipment, pacemakers, dialysis controllers, etc.) 6 Information Processing Equipment (large scale computer systems, etc.) 7 Electric Heating Appliances, Combustion devices (gas fan heaters, oil fan heaters, etc.) 8 Rotary Motion Equipment 9 Security Systems J And any similar types of equipment Operating Conditions and Circuit Design [Maximum power dissipation] 1. Circuit Design · The Maximum power that can be continuously applied under static air at a certain ambient temperature. The Maximum power dissipation under an ambient temperature of 25 °C or less is the same with the rated maximum power dissipation, and Maximum power dissipation beyond 25 °C depends on the Decreased power dissipation curve below. 1.1 Operating Temperature and Storage Temperature When operating a components-mounted circuit, please be sure to observe the “Operating Temperature Range”, written in delivery specifications. Please remember not to use the product under the condition that exceeds the specified maximum temperature. Storage temperature of PCB after mounting Thermistors, which is not operated, should be within the specified “Storage Temperature Range” in the delivery specifications. Maximum power dissipation / Rated maximum power dissipation (%) Decreased power dissipation curve 1.2 Operating Power The electricity applied to between terminals of Thermistors should be under the specified maximum power dissipation. There are possibilities of breakage and burn-out due to excessive self-heating of Thermistors, if the power exceeds maximum power dissipation when operating. Please consider installing protection circuit for your circuit to improve the safety, in case of abnormal voltage application and so on. Thermistors’ performance of temperature detection would be deteriorated if self-heating occurs, even when you use it under the maximum power dissipation. Please consider the maximum power dissipation and dissipation factor. 100 50 25 75 125 Ambient temperature (°C) [Dissipation factor] · The constant amount power required to raise the temperature of the Thermistor 1 °C through self heat generation under stable temperatures.

Chip Mounting Consideration (1) To minimize mechanical stress caused by the warp or bending of a PC board, please follow the recommended Thermistors’ layout below. Prohibited layout (1) When mounting the Thermistors/components on a PC board, the Thermistor bodies shall be free from excessive impact loads such as mechanical impact or stress due to the positioning, pushing force and displacement of vacuum nozzles during mounting. (2) Maintenance and inspection of the Chip Mounter must be performed regularly. (3) If the bottom dead center of the vacuum nozzle is too low, the Thermistor will crack from excessive force during mounting. The following precautions and recommendations are for your reference in use. (a) Set and adjust the bottom dead center of the vacuum nozzles to the upper surface of the PC board after correcting the warp of the PC board. (b) Set the pushing force of the vacuum nozzle during mounting to 1 to 3 N in static load. (c) For double surface mounting, apply a supporting pin on the rear surface of the PC board to suppress the bending of the PC board in order to minimize the impact of the vacuum nozzles. Typical examples are shown in the table below. Recommended layout Layout the Thermistors sideways against the stressing direction (2) The following layout is for your reference since mechanical stress near the dividing/breaking position of a PC board varies depending on the mounting position of the Thermistors. E D Perforation C A B Slit Magnitude of stress A>B=C>D>E (3) The magnitude of mechanical stress applied to the Thermistors when dividing the circuit board in descending order is as follows: push back < slit < V-groove < perforation. Also take into account the layout of the Thermistors and the dividing/breaking method. (4) When the Thermistors are placed near heating elements such as heater, etc., cracks from thermal stresses may occur under following situation: · Soldering the Thermistors directly to heating elements. · Sharing the land with heating elements. If planning to conduct above-mentioned mounting and/or placement, please contact us in advance. Item Single surface mouting Prohibited mounting Crack Recommended mounting The supporting pin does not necessarily have to be positioned beneath the Thermistor. Supporting pin Double surface mounting Separation of Solder Crack Supporting pin (d) Adjust the vacuum nozzles so that their bottom dead center during mounting is not too low. (4) The closing dimensions of the positioning chucks shall be controlled. Maintenance and replacement of positioning chucks shall be performed regularly to prevent chipping or cracking of the Thermistors caused by mechanical impact during positioning due to worn positioning chucks. (5) Maximum stroke of the nozzle shall be adjusted so that the maximum bending of PC board does not exceed 0.5 mm at 90 mm span. The PC board shall be supported by an adequate number of supporting pins. 2.5 Mounting Density and Spaces Intervals between components should not be too narrow to prevent the influence from solder bridges and solder balls. The space between components should be carefully determined. Precautions for Assembly 1. Storage (1) The Thermistors shall be stored between 5 to 40 °C and 20 to 70 % RH, not under severe conditions of high temperature and humidity. (2) If stored in a place where humidity, dust, or corrosive gasses (hydrogen sulfide, sulfurous acid, hydrogen chloride and ammonia, etc.) are contained, the solderability of terminal electrodes will be deteriorated. In addition, storage in a places where the heat or direct sunlight exposure occur will cause mounting problems due to deformation of tapes and reels and components and taping/reels sticking together. (3) Do not store components longer than 6 months. Check the solderability of products that have been stored for more than 6 months before use 3. Selection of Soldering Flux Soldering flux may seriously affect the performance of the Thermistors. The following shall be confirmed before use. (1) The soldering flux should have a halogen based content of 0.1 wt% (converted to chlorine) or below. Do not use soldering flux with strong acid. (2) When applying water-soluble soldering flux, wash the Thermistors sufficiently because the soldering flux residue on the surface of PC boards may deteriorate the insulation resistance on the Thermistors’ surface. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 03 May. 2015 – 13 – Multilayer NTC Thermistors 4. Soldering (b) Preheating: Conduct sufficient pre-heating, and make sure that the temperature difference between solder and Thermistors’ surface is 150 °C or less. (c) Temperature of Iron tip: 300 °C max. (The required amount of solder shall be melted in advance on the soldering tip.) (d) Gradual cooling: After soldering, the Thermistors shall be cooled gradually at room temperature. 4.1 Reflow Soldering The reflow soldering temperature conditions are composed of temperature curves of Preheating, Temp. rise, Heating, Peak and Gradual cooling. Large temperature difference inside the Thermistors caused by rapid heat application to the Thermistors may lead to excessive thermal stresses, contributing to the thermal cracks. The Preheating temperature requires controlling with great care so that tombstone phenomenon may be prevented.

Post Soldering Cleaning 5.1 Cleaning solvent Soldering flux residue may remain on the PC board if cleaned with an inappropriate solvent. This may deteriorate the electrical characteristics and reliability of the Thermistors. 4.2 Hand Soldering Hand soldering typically causes significant temperature change, which may induce excessive thermal stresses inside the Thermitors, resulting in the thermal cracks, etc. In order to prevent any defects, the following should be observed. · The temperature of the soldering tips should be controlled with special care. · The direct contact of soldering tips with the Thermistors and/or terminal electrodes should be avoided. · Dismounted Thermistors shall not be reused. (1) Condition 1 (with preheating) (a) Soldering: Use thread solder (f1 mm or below) which contains flux with low chlorine, developed for precision electronic equipment. 5.2 Cleaning conditions Inappropriate cleaning conditions such as insufficient cleaning or excessive cleaning may impair the electrical characteristics and reliability of the Thermistors. (1) Insufficient cleaning can lead to: (a) The halogen substance found in the residue of the soldering flux may cause the metal of terminal electrodes to corrode. (b) The halogen substance found in the residue of the soldering flux on the surface of the Thermistors may change resistance values. (c) Water-soluble soldering flux may have more remarkable tendencies of (a) and (b) above compared to those of rosin soldering flux. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 03 May. 2015 – 14 – Multilayer NTC Thermistors (2) Dividing/Breaking of the PC boards shall be done carefully at moderate speed by using a jig or apparatus to protect the Thermistors on the boards from mechanical damage. (3) Examples of PCB dividing/breaking jigs: The outline of PC board breaking jig is shown below. When PC boards are broken or divided, loading points should be close to the jig to minimize the extent of the bending Also, planes with no parts mounted on should be used as plane of loading, in order to prevent tensile stress induced by the bending, which may cause cracks of the Thermistors or other parts mounted on the PC boards. (2) Excessive cleaning can lead to: (a) When using ultrasonic cleaner, make sure that the output is not too large, so that the substrate will not resonate. The resonation causes the cracks in Varistors and/or solders, and deteriorates the strength of the terminal electrodes. Please follow these conditions for Ultrasonic cleaning: Ultrasonic wave output : 20 W/L max. Ultrasonic wave frequency : 40 kHz max. Ultrasonic wave cleaning time : 5 min. max. 5.3 Contamination of Cleaning solvent Cleaning with contaminated cleaning solvent may cause the same results as insufficient cleaning due to the high density of liberated halogen. Outline of Jig 6. Inspection Process The pressure from measuring terminal pins might bend the PCB when implementing circuit inspection after mounting Thermistors on PCB, and as a result, cracking may occur. (1) Mounted PC boards shall be supported by an adequate number of supporting pins on the back with bend settings of 90 mm span 0.5 mm max. (2) Confirm that the measuring pins have the right tip shape, are equal in height, have the right pressure, and are set in the correct positions. The following figures are for your reference to avoid bending the PC board. Item Prohibited setting PC board V-groove PC board splitting jig Prohibited dividing Loading direction Loading point PC board Recommended setting Recommended dividing PC board Chip component Loading direction V-groove Chip component Loading point V-groove Check pin Check pin 9. Mechanical Impact Bending of PC board Separated, Crack (1) The Thermistors shall be free from any excessive mechanical impact. The Thermistor body is made of ceramics and may be damaged or cracked if dropped. N eve r use a T h ermisto r w hich has be en dropped; their quality may be impaired and failure rate increased. (2) When handling PC boards with Thermistors mounted on them, do not allow the Thermistors to collide with another PC board. When mounted PC boards are handled or stored in a stacked state, the corner of a PC board might strike Thermistors, and the impact of the strike may cause damage or cracking and can deteriorate the withstand voltage and insulation resistance of the Thermistor. Supporting pin 7. Protective Coating When the surface of a PC board on which the Thermistors have been mounted is coated with resin to protect against moisture and dust, it shall be confirmed that the protective coating does not affect the performance of Varistors. (1) Choose the material that does not emit the decomposition and/or reaction gas. The Gas may affect the composing members of the Varistors. (2) Shrinkage and expansion of resin coating when curing may apply stress to the Varistors and may lead to occurrence of cracks. 8. Dividing/Breaking of PC Boards Mounted PCB (1) Please be careful not to stress the substrate with bending/twisting when dividing, after mounting components including Varistors. Abnormal and excessive mechanical stress such as bending or torsion shown below can cause cracking in the Thermistors. Bending Crack Crack Floor Other Torsion The various precautions described above are typical. For special mounting conditions, please contact us. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.

Chip Mounting Consideration (1) To minimize mechanical stress caused by the warp or bending of a PC board, please follow the recommended Thermistors’ layout below. Prohibited layout (1) When mounting the Thermistors/components on a PC board, the Thermistor bodies shall be free from excessive impact loads such as mechanical impact or stress due to the positioning, pushing force and displacement of vacuum nozzles during mounting. (2) Maintenance and inspection of the Chip Mounter must be performed regularly. (3) If the bottom dead center of the vacuum nozzle is too low, the Thermistor will crack from excessive force during mounting. The following precautions and recommendations are for your reference in use. (a) Set and adjust the bottom dead center of the vacuum nozzles to the upper surface of the PC board after correcting the warp of the PC board. (b) Set the pushing force of the vacuum nozzle during mounting to 1 to 3 N in static load. (c) For double surface mounting, apply a supporting pin on the rear surface of the PC board to suppress the bending of the PC board in order to minimize the impact of the vacuum nozzles. Typical examples are shown in the table below. Recommended layout Layout the Thermistors sideways against the stressing direction (2) The following layout is for your reference since mechanical stress near the dividing/breaking position of a PC board varies depending on the mounting position of the Thermistors. E D Perforation C A B Slit Magnitude of stress A>B=C>D>E (3) The magnitude of mechanical stress applied to the Thermistors when dividing the circuit board in descending order is as follows: push back < slit < V-groove < perforation. Also take into account the layout of the Thermistors and the dividing/breaking method. (4) When the Thermistors are placed near heating elements such as heater, etc., cracks from thermal stresses may occur under following situation: · Soldering the Thermistors directly to heating elements. · Sharing the land with heating elements. If planning to conduct above-mentioned mounting and/or placement, please contact us in advance. Item Single surface mouting Prohibited mounting Crack Recommended mounting The supporting pin does not necessarily have to be positioned beneath the Thermistor. Supporting pin Double surface mounting Separation of Solder Crack Supporting pin (d) Adjust the vacuum nozzles so that their bottom dead center during mounting is not too low. (4) The closing dimensions of the positioning chucks shall be controlled. Maintenance and replacement of positioning chucks shall be performed regularly to prevent chipping or cracking of the Thermistors caused by mechanical impact during positioning due to worn positioning chucks. (5) Maximum stroke of the nozzle shall be adjusted so that the maximum bending of PC board does not exceed 0.5 mm at 90 mm span. The PC board shall be supported by an adequate number of supporting pins. 2.5 Mounting Density and Spaces Intervals between components should not be too narrow to prevent the influence from solder bridges and solder balls. The space between components should be carefully determined. Precautions for Assembly 1. Storage (1) The Thermistors shall be stored between 5 to 40 °C and 20 to 70 % RH, not under severe conditions of high temperature and humidity. (2) If stored in a place where humidity, dust, or corrosive gasses (hydrogen sulfide, sulfurous acid, hydrogen chloride and ammonia, etc.) are contained, the solderability of terminal electrodes will be deteriorated. In addition, storage in a places where the heat or direct sunlight exposure occur will cause mounting problems due to deformation of tapes and reels and components and taping/reels sticking together. (3) Do not store components longer than 6 months. Check the solderability of products that have been stored for more than 6 months before use 3. Selection of Soldering Flux Soldering flux may seriously affect the performance of the Thermistors. The following shall be confirmed before use. (1) The soldering flux should have a halogen based content of 0.1 wt% (converted to chlorine) or below. Do not use soldering flux with strong acid. (2) When applying water-soluble soldering flux, wash the Thermistors sufficiently because the soldering flux residue on the surface of PC boards may deteriorate the insulation resistance on the Thermistors’ surface. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 00 – 23 – Jun. 2015 NTC Thermistors for automotive devices (chip type) 4. Soldering (b) Preheating: Conduct sufficient pre-heating, and make sure that the temperature difference between solder and Thermistors’ surface is 150 °C or less. (c) Temperature of Iron tip: 300 °C max. (The required amount of solder shall be melted in advance on the soldering tip.) (d) Gradual cooling: After soldering, the Thermistors shall be cooled gradually at room temperature. 4.1 Reflow Soldering The reflow soldering temperature conditions are composed of temperature curves of Preheating, Temp. rise, Heating, Peak and Gradual cooling. Large temperature difference inside the Thermistors caused by rapid heat application to the Thermistors may lead to excessive thermal stresses, contributing to the thermal cracks. The Preheating temperature requires controlling with great care so that tombstone phenomenon may be prevented.

Post Soldering Cleaning 5.1 Cleaning solvent Soldering flux residue may remain on the PC board if cleaned with an inappropriate solvent. This may deteriorate the electrical characteristics and reliability of the Thermistors. 4.2 Hand Soldering Hand soldering typically causes significant temperature change, which may induce excessive thermal stresses inside the Thermitors, resulting in the thermal cracks, etc. In order to prevent any defects, the following should be observed. · The temperature of the soldering tips should be controlled with special care. · The direct contact of soldering tips with the Thermistors and/or terminal electrodes should be avoided. · Dismounted Thermistors shall not be reused. (1) Condition 1 (with preheating) (a) Soldering: Use thread solder (f1 mm or below) which contains flux with low chlorine, developed for precision electronic equipment. 5.2 Cleaning conditions Inappropriate cleaning conditions such as insufficient cleaning or excessive cleaning may impair the electrical characteristics and reliability of the Thermistors. (1) Insufficient cleaning can lead to: (a) The halogen substance found in the residue of the soldering flux may cause the metal of terminal electrodes to corrode. (b) The halogen substance found in the residue of the soldering flux on the surface of the Thermistors may change resistance values. (c) Water-soluble soldering flux may have more remarkable tendencies of (a) and (b) above compared to those of rosin soldering flux. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 00 – 24 – Jun. 2015 NTC Thermistors for automotive devices (chip type) (2) Dividing/Breaking of the PC boards shall be done carefully at moderate speed by using a jig or apparatus to protect the Thermistors on the boards from mechanical damage. (3) Examples of PCB dividing/breaking jigs: The outline of PC board breaking jig is shown below. When PC boards are broken or divided, loading points should be close to the jig to minimize the extent of the bending Also, planes with no parts mounted on should be used as plane of loading, in order to prevent tensile stress induced by the bending, which may cause cracks of the Thermistors or other parts mounted on the PC boards. (2) Excessive cleaning can lead to: (a) When using ultrasonic cleaner, make sure that the output is not too large, so that the substrate will not resonate. The resonation causes the cracks in Varistors and/or solders, and deteriorates the strength of the terminal electrodes. Please follow these conditions for Ultrasonic cleaning: Ultrasonic wave output : 20 W/L max. Ultrasonic wave frequency : 40 kHz max. Ultrasonic wave cleaning time : 5 min. max. 5.3 Contamination of Cleaning solvent Cleaning with contaminated cleaning solvent may cause the same results as insufficient cleaning due to the high density of liberated halogen. Outline of Jig 6. Inspection Process The pressure from measuring terminal pins might bend the PCB when implementing circuit inspection after mounting Thermistors on PCB, and as a result, cracking may occur. (1) Mounted PC boards shall be supported by an adequate number of supporting pins on the back with bend settings of 90 mm span 0.5 mm max. (2) Confirm that the measuring pins have the right tip shape, are equal in height, have the right pressure, and are set in the correct positions. The following figures are for your reference to avoid bending the PC board. Item Prohibited setting PC board V-groove PC board splitting jig Prohibited dividing Loading direction Loading point PC board Recommended setting Recommended dividing PC board Chip component Loading direction V-groove Chip component Loading point V-groove Check pin Check pin 9. Mechanical Impact Bending of PC board Separated, Crack (1) The Thermistors shall be free from any excessive mechanical impact. The Thermistor body is made of ceramics and may be damaged or cracked if dropped. N eve r use a T h ermisto r w hich has be en dropped; their quality may be impaired and failure rate increased. (2) When handling PC boards with Thermistors mounted on them, do not allow the Thermistors to collide with another PC board. When mounted PC boards are handled or stored in a stacked state, the corner of a PC board might strike Thermistors, and the impact of the strike may cause damage or cracking and can deteriorate the withstand voltage and insulation resistance of the Thermistor. Supporting pin 7. Protective Coating When the surface of a PC board on which the Thermistors have been mounted is coated with resin to protect against moisture and dust, it shall be confirmed that the protective coating does not affect the performance of Varistors. (1) Choose the material that does not emit the decomposition and/or reaction gas. The Gas may affect the composing members of the Varistors. (2) Shrinkage and expansion of resin coating when curing may apply stress to the Varistors and may lead to occurrence of cracks. 8. Dividing/Breaking of PC Boards Mounted PCB (1) Please be careful not to stress the substrate with bending/twisting when dividing, after mounting components including Varistors. Abnormal and excessive mechanical stress such as bending or torsion shown below can cause cracking in the Thermistors. Bending Crack Crack Floor Other Torsion The various precautions described above are typical. For special mounting conditions, please contact us. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
