Vishay’s QPL RNC90Y and Non-QPL S555 Bulk Metal® Foil established reliability resistors

17 JUNE 2009

Vishay Intertechnology, Inc. announced that it has extended the resistance tolerance of the QPL RNC90Y family of established reliability Bulk Metal® Foil resistors down to ±0.005%. For designers requiring higher or lower resistance values than the QPL range, but with the same performance capabilities, a S555 non-QPL version of the device is also available. As “R” level established reliability resistors, RNC90Y devices are military-qualified to MIL PRF 55182/9, the standard for military and aerospace applications requiring superior performance such as tighter tolerances, lower temperature coefficients, and better long-term stability. The enhanced devices offer a broad resistance range of 4.99W to 121kW and a load-life stability.
