The need for even lower resistance value ranges is already becoming evident, as is the need for these resistors to handle more power. The industry-wide trend is the emergence of smaller and smaller products. Token Electronics offers a wide variety of current sensing products from the industry to military standards, such as current sense in Thin-Film / Thick-Film Technology, Bare Element Resistors, and Open Air Shunts. This enables Token to present an astounding number of possible solutions for any circuit design needs. Applications of Current Detecting Resistors Token’s TCS and CS Series unique form factor provides automotive designers with several advantages. Both TCS and CS Series are ideal for applications involving window lift motors, fuel pump systems, seat belt pretensioners, and pulsewidth modulator feedback. The wider resistive element and lower resistance enables higher current to pass through the device. Token’s LRC ultra low ohmic metal strip chip series provides the inherent ability to flex slightly and offers stress relief during extreme temperature cycling on typical or metal substrates. This LRC series is suitable for switch power supply applications (DC-DC Converter, Charger, Adaptor) and power management of monitor. The open air design of bare element resistor LRA and LRB Series provide a far cooler operation by allowing more air flow under the resistive element to keep excess heat from being transmitted to the PC board. They are suitable for high power AC/DC detection of power supply circuit. Token axial moulded BWL series provides power rating up to 10 watts and lower resistance 0.005Ω, is ideal for all types of current sensing applications including switching and linear power supplies, instruments and power amplifiers.

Generally, a resistor manufacturer will offer their most popular devices as standards creating a reference for Engineers to design from. Typically, and especially true in the Current Sensing category, a standard device is available for most common applications. However, for applications requiring parameters that are not currently considered industry standards, Token is uniquely equipped to offer design and development services at comparatively lower costs than our competitors. In this case, the following information is required to effectively design a current sensing resistor: 02 of 56 http://www.token.com.tw/ rfq token.com.tw Version 2010 TOKEN Design & Select Current Sense Resistors Design & Select Current Sense Resistors Point 1 - Power Rating Calculate the power dissipation under operating conditions Equation: Pavg = IRMS2 × R; where Power (P), Current (I), Root Mean Square (RMS), Resistance (R).Allowing for transient or fault conditions and high ambient temperature if applicable, select the required power rating.For many current sense products, only the maximum temperature of the solder joints limits the power rating.Power rating is thus a function of the PCB layout design as well as of component selection (see point 4.). Point 2 - Resistance Value Determine the minimum suitable resistance value. This is the lowest value of peak sense voltage consistent with an acceptable signal to noise ratio, divided by the peak current to be measured. Point 3 - Temperature Coefficient of Resistance (TCR) Establish the accuracy needed in terms of a tolerance on the value and of sensitivity to temperature. The latter factor is quoted as Temperature Coefficient of Resistance (TCR), defined as the value change in parts per million for a 1°C temperature rise. It is generally higher for low value resistors because the metallic leads or terminations, which have a very high TCR, make up a significant part of the total resistance value. To achieve acceptable accuracy it is normally necessary to make four-terminal (Kelvin) connections to the resistor. This means connecting the current carrying tracks and the voltage sense tracks directly to the component pads. Even when this is done, there is still some pad area and solder in series with the resistor, which may compromise the actual tolerance and TCR of the soldered part. For very high accuracy or very low values, a four-terminal resistor type is the best choice. Point 4 - PCB Layout Care must be taken when laying out a PCB if the stated performance of a sense resistor is to be achieved. The current carrying tracks should be as wide as possible, using multiple layers connected by many vias near the component pad. This also improves the heatsinking of the joints. The best way to make four-terminal connections to a two-terminal through-hole resistor is to use different sides of the PCB for the current and voltage connections. Failing this, current and voltage tracks should connect to opposite sides of the component pad. Version 2010 http://www.token.com.tw/ rfq token.com.tw 03 of 56 TOKEN Design & Select Current Sense Resistors In order to avoid interference from stray magnetic fields, the loop area contained by the sense resistor, the voltage sense tracks and the sense circuit input should be minimised. This means keeping the sense circuitry as close as possible to the sense resistor and running the voltage sense tracks close to each other. Point 5 - High Frequency Applications Where transient or AC currents involving high frequencies are to be sensed, the self-inductance of the resistor must be minimised. Wirewound or spiralled film parts should be avoided, in favour of bulk metal or low value chips. Point 6 - High Heat Dissipation When using a metallic element shunt with high heat dissipation and low sense voltage, consideration may need to be given to thermoelectric voltages. The junction between a metallic resistance element and metal terminations acts as a thermocouple, generating a voltage proportional to the temperature difference across it. A leaded metallic element sense resistor is therefore like two thermocouples back to back. This means that, if the temperature differences across both junctions are equal, the error voltage is cancelled out. This is achieved by making the design thermally symmetrical, namely, by presenting both terminals with similar heatsinking and by keeping any other heat sources thermally distant. 04 of 56 http://www.token.com.tw/ rfq token.com.tw Version 2010 TOKEN Terminology & Glossary Terminology Glossary of Current Sensing Resistors What is a Current Sensing Resistor Current sensing products are the newest and fastest growing resistive products in the industry today. As with most passive products, the majority of new designs are surface mount. These resistors are used to monitor the current in a circuit and translate the amount of current in that circuit into a voltage that can be easily measured and monitored. Current Detecting Resistors Due to the increase in sales of notebook PCs, the demand for the DC/DC converter has shown rapid growth because of its high-energy conversion efficiency, and its precise current-limiting capability. However, to ensure the performance of the multiple output DC/DC converter, the current limiting voltage must be detected precisely to protect an expensive notebook PC from an overload, which is generally due to shorts within the capacitors used in these devices. For high-energy conversion efficiency various control ICs have been developed that utilize resistive components. To achieve the perfect cutoff mode of the DC load current at the programmed current-limiting voltage of the control IC, a very stable and accurate sense resistor with the following characteristics is required for precise voltage comparison. ● Very Low Ohmic Value should be below 25mΩ for minimizing power consumption at the current sensing resistor. ● Tight Tolerance must be ±1% or tighter for maximizing the current supply within the limit of accept able current. ● Low TCR is required for current sensing across the ambient temperature range of 0°C to 60°C. ● Low Thermal EMF for an accurate comparison between the programmed current-limiting voltage of the control IC and the detected voltage. Furthermore, the self-inductance should be for high frequency applications. Recommended types are general purpose current sensing products or a flame retardant type.

How Four Terminal Sense Resistor Work High precision resistors used for current sensing are usually low ohmic value devices suitable for four terminal connection. To use a 4-terminal resistor, we force a current from Terminal 1 to Terminal 2. It’s current, so the unknown resistances attached to Terminal 1 and Terminal 2 don’t affect the amount of the current. The same number of electrons per second flow through from T1 to T2, regardless of the resistance. A voltmeter measures the resulting voltage drop across the ultra-precise resistor, measuring through the unknown resistors attached to Terminal 3 and Terminal 4. The voltmeter’s input impedance is very, very high compared to the unknown resistors, so the unknown resistors have essentially zero effect (typically less than 0.1 parts-per-million). So the current flows through the 0.100 ohm resistor, unaffected by the unknown resistors, and we measure the voltage across the 0.100 ohm resistor, unaffected by the unknown resistors. And that’s how a 4-terminal resistor works!

Hot-Spot Temperature The maximum temperature measured on the resistor due to both internal heating and the ambient operating temperature. Low Profile Components designed with “lower than standard heights”, to save space and allow clearance when mounted on PCBs. Maximum Working Voltage The maximum specified voltage that may be applied across a resistor. PPM Parts per million. The terminology used when describing the temperature coefficient. Screen The process of printing a network pattern of thick-film ink or paste onto a substrate by means of a squeegee applied to a photo-etched wire-mesh “silk screen” or metal mask. Current Shunt Resistors Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a type of current sensor. SMT/SMD Surface-mount technology/surface-mount device. Zero Ohm Resistors Products that look like resistors, but actually have no resistance (very very low resistance) and instead perform as jumpers.

From a certified supplier offering the automotive quality, Token’s LRC Series gives all round superior performance for current sensing in lamp detection, mirrors, window lift, steering and seat controls. As a first instance, the LRC Series displays enhanced power handling capabilities, against other technologies. Thermal conductivity is important for chip resistors - little heat is dissipated directly into the air, and instead, is conducted out through the solder pads. The heat generated from the specially constructed LRC resistor is more readily dispersed, therefore preventing localised heating, which contributes to TCR and thermal EMF errors, premature aging and possible scorching of the PC board. They are rated for ambient operation from -55°C to +170°C. The LRC Series is RoHS compliant and lead free. Contact us with your specific needs.

These smaller sizes save space on the circuit board, allowing the production of smaller and lighter products. The new series complements Token’s existing LRC Series, offering metal resistive film on ceramic construction but providing increased choice for product designers in the form of more smaller sizes options of 0201, 0402, 0603, 0805, 1206, 2010, 2512, 1225, 3720, and 7520. Designed for current detecting in power electronic systems, the fully RoHS compliant CS series is suitable for a range of applications including the monitoring of power usage and battery life; and provision of output protection for power supplies; as well as for a range of consumer and automotive products such as satellite navigation, handheld PDAs and digital set-top boxes. The series offers ohmic values as low as 1mΩ to minimise power consumption and has an ambient temperature range of -55°C to +155°C. Exhibiting a resistance range up to 1Ω and excellent heat dissipation qualities, the series offers designers enhanced power handling capabilities and protection from the threat of localised heating, resulting in the production of a more energy efficient product. As demand continues to grow for reduced size, handheld and portable devices operating at low voltages, designers will look to manufacturers to produce smaller and smaller current sense resistors. Token expects that demand for its latest range of small size resistors will be high. Contact us with your specific needs.

Devices from the Token Electronics’ TCS series use a thin film construction that enables them to achieve precision resistance tolerances, low noise and long-term stability. The Token TCS Series precision resistors are nichrome thin film chip resistors with a temperature coefficient of resistance of just ±50PPM/°C and tolerances of ±0.5%. They offer excellent stability at high frequencies and are suitable for operating high voltages with more options in the smaller form sizes of 0402, 0603, 0402, 0805, 1206, 2010, and 2512. The full range of values is from 50mΩ to 1Ω. This low ohmic devices are particularly suited to car engine management units to act as current sensing shunt resistors. The TCS series is fully RoHS compliant and is supplied in tape and reel packaging ready for use with automated assembly processes. Contact us with your specific needs. Features - Thin Film Process. Resistance Values from 50mΩ to 1Ω. Very Tight Tolerance from ±1% to ±0.5%. RoHS Requirments with Pb-free Terminations. Extremely Low TCR from ±200 PPM/°C to ±50PPM/°C.

The LRA Series is designed for applications requiring the transfer of heat away from circuits and solder joints. Available in 0.5W, 1W, and 1.5W rating, the resistor is being specified for current sensing, feedback, current detective, supper low inductance, as well as surge and pulse applications. The hot spot on the LRA resistor is approximately 0.2 degrees higher than on a typical metal strip chip resistor. This results in an increased thermal path for the LRA, reducing heat transfer into the solder joints and circuits. The flameproof LRA Series resistors are constructed of a wire resistive element with welded copper leads to prevent solder wicking, which can change the device’s resistance value in the circuit by as much as 30%. Because of this, the device is ideal for thermally harsh environments, including automotive and aerospace applications, as well as enclosed, poorly ventilated circuits in applications such as laptop computers. The LRA Open Air Series feature a reduced pitch, or spacing between the leads on the circuit board (with a corresponding increase in the board mounted profile), when compared to the standard Token LRB Series devices. The LRA resistors are rated for 1W or 1.5W at 70°C, with resistance values from 0.1Ω to 0.003Ω and tolerances down to ±1%. Operating temperature range is -50°C to 300°C. The LRA Series is available in bulk packaging in 200 increments. Token will also produce devices outside these specifications to meet customer requirements. A lead-free RoHScompliant version is available, as is a non-inductive version for high frequency applications. Contact us with your specific needs.

Preview In response to requests from power electronics design engineers with the means to squeeze more current-sensing capability into crowded power supply designs, Token Electronics has developed a “tight pitch” version of its open air metal element current sensing resistor with ratings as high as 5W in a reduced PC board footprint and longer thermal path. Designated the OAR Series, these open-air through-hole devices offer a high current, flameproof alternative to conventional axial devices and flat chips for current-sense circuits where PC board space is at a premium. The resistor’s footprint is reduced by extending the height of the device above the board, thus keeping the resistor element’s “hot spot” safely off the PC board and providing for increased air circulation under it, which in turn provides increased heat dissipation and cooler operation. The OAR devices with increased height improve cooling efficiency, and because many power supply designs are already tightly-packed at the PC board level, the additional height does not create any profile issues. The OAR series resistors feature a reduced pitch, or spacing between the leads on the circuit board with a corresponding increase in the board mounted profile. The OAR Series resistors are power rated for 1W, 2W, 3W, or 5W at 85°C, with resistance values from 0.05Ω to 0.005Ω, with tolerances down to ±1%. They feature TCRs as low as ±50ppm/°C and inductance values in the single-digit nanohenry range (10 nH Max.). Operating temperature range is -40°C to +125°C. The flameproof OAR resistors are constructed of a wire resistive element with welded copper leads to prevent solder wicking, which can change the device’s resistance value in the circuit by as much as 30%. The OAR Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical requirements and special applications,please contact us with your specific needs.

Preview Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a type of current sensor. A wide range of precision shunts, designed for use with kilowatt-hour meters and other high-current applications where a high level of accuracy is required, is now available from Token Electronics. The interchangeable shunts (FL) are used to multiply the measuring range of measuring instruments and designed for PCB and busbar mounting, are manufactured from electron beam welded copper and manganin, and have low temperature coefficients. Featuring low inductance values, shunts FL series can handle permanent currents of up to 10000A at voltage 75 mV. FLQ-54 type shunt is made of precision alloy board. It’s copper terminals spot welded by silver alloy ensure extremely high electric capability. The construction provides a kind of excellent stability and high overloaded ability non-inductive resistor, applied widely as current limited, current balance or sampling sense in communication system, electric equipment and auto-controlling electrical circuit. The FL Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical requirements and special applications, please contact us with your specific needs. Power Rating : Watts (W) = Current (I2) x Resistance Value (R) - The heat produced is power measured in Watts (W). - In practice current shunts are often rated to be used continuously at only 2/3 of their “rated current”. - Because current shunts are resistors and dissipate heat from the current flowing through them, they get hot. - Since that heat can change their resistance and even permanently damage the shunt, current shunts are often given a power rating or a derating factor. Calculate Current : Current (I) = Voltage (V) / Resistance Value (R) - Then knowing the resistance of the current shunt you can calculate the current using Ohm’s law. - By inserting a current shunt into a circuit whose current you want to measure your can find the current by measuring the voltage drop across the shunt.

The Kelvin (or four-terminal) configuration enables current to be applied through two opposite terminals and a sensing voltage to be measured across the other two terminals, eliminating the resistance and temperature coefficient of the terminals for a more accurate current measurement. The four terminal resistors are a new version of Token’s (LSQ) Current Sense Family Series which was specially designed for use in a Kelvin configuration where a current is applied through two opposing leads and sensing voltage is measured across the other two leads. Token LSQ series is specifically designed for low resistance applications requiring the highest accuracy and temperature stability. The advantages of Kelvin configuration enable the resistance and temperature coefficient of the leads to be effectively eliminated. The need to connect to the leads at precise test points is eliminated, allowing for tighter tolerance on the end application. Also results in a lower temperature coefficient of resistance and lower self-heating drift which may be experienced on two-terminal resistors. Token will also produce low ohm resistor LSQ series outside these specifications to meet customer requirements. Contact us with your specific needs.
