CODING INTERNATIONAL CO LTD

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 it 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 ohm to 1 Mohm with resistance tolerances of ± 5 % and ± 1 %, as well as 0 ohm 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.

Samples and production quantities of the D..EN802 and CRCW….EN802 resistors are available now, with lead times of six to eight weeks for standard orders. Pricing varies by case size, resistance value, tolerance, TCR, and failure rate level.
