Designed for use where extremely high stability is required, such as in avionics and test data logging applications, the WA and WB series metal foil resistors use a two wire lead construction for mechanical stress relief. They also employ a metal foil resistor element to provide reliable solutions for A/D designs. Load life stability is ±150 ppm maximum (2,000 hours at rated power) and TCRs as low as ±2.5 ppm/°C and resistance tolerances as tight as 0.005% are available within an eight week lead time. The WA resistors are in the process of being qualified to Mil-PRF-55182/RNC90Y and NASA S-311 specs. For further information and pricing, contact WILBRECHT ELECTRONICS INC., St. Paul, MN.
