Keywords:resistor? termination plating? Pb-bearing?

Vishay Intertechnology Inc. has unveiled a couple of lead (Pb)-free and Pb-bearing thick film chip resistors with IECQ-CECC approval. Both devices are approved to EN 140401-802, Version Ato meet the needs of the industrial electronics industry and EN 140401-802, Version Efor military, avionics and space applications. Version E devices feature established reliability with an assessed failure rate level of E6, stated the company.

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

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

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

Samples and production quantities of the D.. EN802 and CRCW.... EN802 resistors are available with lead times of six to eight weeks for standard orders.
