Vishay PATT Automotive Thin Film Chip Resistors Vishay PATT Automotive Thin Film Chip Resistors are rated for full power at 155 °C and are AEC-Q200 certified. Providing nearly a 100ºC extension in operating temperature range over traditional thin film chip resistors, Vishay's PATT series features high-temperature operation to +155ºC with 100% power, derated linearly to 0 mW power at +250ºC. With low absolute TCR down to ±25 ppm/ºC, tolerances to ±0.1%, and a load-life stability of <,0.2%, the Vishay Dale thin film resistor is optimized for the low-noise, single-signal processing required to compensate for low offset and temperature drift in high-temperature environments.
