Thick Film Chip Resistors

Vishay Intertechnology, Inc. released lead (Pb)-free and lead (Pb)-bearing thick film chip resistors with IECQ-CECC approval. Both devices are offered in two versions: approved to EN 140401-802, Version A, to meet the needs of the industrial electronics industry; and approved to EN 140401-802, Version E, for military, avionics, and space applications. Version E devices feature established reliability with an assessed failure rate level of E6.

The CRCW….EN802 offers pure tin termination plating on a nickel barrier, which has been proven under extensive testing to provide immunity against tin whisker growth. The resistor complies with the RoHS Directive 2002/95/EC, and is compatible with lead (Pb)-free and lead (Pb)-containing soldering processes.

The D..EN802 resistor offers SnPb termination plating on a nickel barrier, with a minimum lead content of 10 %. This version is optimized for customers depending on matured technologies, including a purely lead (Pb)-bearing assembly process.

Both devices released today are offered in the 0805 and 1206 case sizes and provide TCR of ± 200 ppm/K, ± 100 ppm/K, and ± 50 ppm/K. The resistors feature a resistance range of 1 Ω to 1 MΩ with resistance tolerances of ± 5 % and ± 1 %, as well as 0 Ω jumpers. Devices in the 0805 case size offer a rated power dissipation of 0.125 W and an operating voltage of 150 V, while resistors in the 1206 case size feature a rated dissipation of 0.250 W and an operating voltage of 200 V.
