Foil Resistors Are Highly Stable

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.
