However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. 1) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly. 2) Film temperatures above the specified range may be permissible, e.g. 175 °C.

A homogeneous and dense carbon film is deposited on a high grade ceramic body (85 % Al2O3). Nickel plated steel termination caps are firmly pressed on the coated rods. A special laser is used to achieve the target value by smoothly cutting a helical groove in the resistive layer without damaging the ceramics. The resistors are covered by protective coating designed for electrical, mechanical and climatic protection.The terminations receive a final pure tin on nickel plating. Four color code rings designate the resistance value and tolerance in accordance with IEC 60 062*. Where applicable the resistors are tested in accordance with EN 140401-803 (superseding CECC 40401-803) which refers to EN 60115-1, EN 140400 and the variety of enviromental text procedures of the IEC 60068* series. Vishay BEYSCHLAG has achieved "Approval of Manufacturer" in accordance with IEC QC 001002-3, clause 2. The release certificate for “Technology Approval Schedule” in accordance with CECC 240001 based on IEC QC 001002-3, clause 6 is granted for the Vishay BEYSCHLAG manufacturing process. Note: * The quoted IEC standards are also released as EN standards with the same number and identical contents. The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. Only accepted products are laid directly into the blister tape in accordance with IEC 60 286-3*. ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapour phase as shown in IEC 61760-1*. Excellent solderability is proven, even after extended storage in excess of 10 years. The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions. The resistors are completely lead (Pb)-free, the pure tin plating provides compatibility with lead (Pb)-free soldering processes. The immunity of the plating against tin whisker growth has been proven under extensive testing. All products comply with the GADSL1) and the CEFICEECA-EICTA2) list of legal restrictions on hazardous substances. This includes full compliance with the following directives: • 2000/53/EC End of Vehicle life Directive (ELV) and Annex II (ELV II) • 2002/95/EC Restriction of the use of Hazardous Substances Directive (RoHS) • 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE) 1) Global Automotive Declarable Substance List, see www.gadsl.org 2) CEFIC (European Chemical Industry Council), EECA (European Electronic Component Manufacturers Association), EICTA (European trade organisation representing the information and communications technology and consumer electronics), see www.eicta.org -> issues -> environment policy -> chemicals -> chemicals for electronics Document Number: 28717 Revision: 18-Jul-06 For technical questions contact: [email protected] www.vishay.com 61 CMA 0204 Vishay Beyschlag High Pulse Load MELF Resistor Power Dissipation P FUNCTIONAL PERFORMANCE 1 CMA 0204 W 0.5 0 - 50 0 50 70 100 C 150 Ambient Temperature ϑ amb Power Dissipation P Derating - Standard Operation 1 CMA 0204 W 0.5 0 - 50 0 50 70 100 C 150 Ambient Temperature ϑ amb Pulse Load Pmax Derating - Power Operation CMA 0204 100 W 10 1 0.1 10 µs 100 µs 1 ms 10 ms 100 ms 1s 10 s Pulse Duration ti Single Pulse www.vishay.com 62 Maximum pulse load, single pulse; applicable if P 0 and n ≤ 1000 and U ≤ Umax; for permissible resistance change equivalent to 8000 h operation For technical questions contact: [email protected] Document Number: 28717 Revision: 18-Jul-06 CMA 0204 Vishay Beyschlag Continuous Pulse Load Pmax High Pulse Load MELF Resistor CMA 0204 100 W 10 1 0.1 10 µs 100 µs 1 ms 10 ms 100 ms 10 s 1s Pulse Duration ti Maximum pulse load, continuous pulses; applicable if P ≤ P (ϑ amb) and U ≤ Umax; for permissible resistance change equivalent to 8000 h operation Pulse Voltage Umax Continuous Pulses CMA 0204 1 kV 100 V 10 µs 100 µs 1 ms 10 ms 100 ms 1s 10 s Pulse Duration ti Pulse Voltage U Pulse Voltage Maximum pulse voltage, single and continuous pulses; applicable if P ≤ Pmax; for permissible resistance change equivalent to 8000 h operation 1 kV 100 V CMA 0204 10 V 10 Ω 100 Ω 1 kΩ 10 kΩ 100 kΩ 1 MΩ Resistance Value R 1.2/50 Document Number: 28717 Revision: 18-Jul-06 Pulse load rating in accordance with IEC 60115-1, 4.27; 1,2 µs/50 µs; 5 pulses at 12 s intervals; for permissible resistance change 0.5 % Pulse For technical questions contact: [email protected] www.vishay.com 63 CMA 0204 Pulse Voltage U Vishay Beyschlag High Pulse Load MELF Resistor CMA 0204 1 kV 100 V 10 V 100 Ω 10 Ω 1 kΩ 10 kΩ 100 kΩ 1 MΩ Resistance Value R Temperature Coefficient 10/700 Pulse Pulse load rating in accordance with IEC 60115-1, 4.27; 10 µs/700 µs; 10 pulses at 1 minute intervals; for permissible resistance change 0.5 % CMA 0204 - 100 ppm/K - 200 - 300 - 400 - 500 10 Ω 100 Ω 1 kΩ 10 kΩ 100 kΩ 1 MΩ 10 MΩ Resistance Value R Temperature coefficient of resistance Current Noise A1 Temperature Coefficient (TCR) CMA 0204 1 µV/V 0.1 0.01 100 Ω 1 kΩ 10 kΩ 100 kΩ 1 MΩ Resistance Value R In accordance with IEC 60 195 Current Noise - A1 www.vishay.com 64 For technical questions contact: [email protected] Document Number: 28717 Revision: 18-Jul-06 CMA 0204 High Pulse Load MELF Resistor Vishay Beyschlag TESTS AND REQUIREMENTS Essentially all tests are carried out in accordance with the following specifications: EN 60115-1, generic specification EN 140400, sectional specification EN 140401-803, detail specification Unless otherwise specified the following values apply: Temperature: 15 °C to 35 °C Relative humidity: 45 % to 75 % Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
