On June 20, Vishay announced a new series of QPL MIL-PRF-55342-qualified surface-mount chip resistors that provides established reliability with an "R" level failure rate of 0.01 % per 1000 hours. Built using a moisture-resistant tantalum nitride resistive film technology, the new E/H (Ta2N) resistors offer enhanced specifications for military and aerospace applications, involving tolerances to 0.1 % and TCR of 25 ppm/°C. The Vishay Dale Thin Film QPL resistors released on June 20 are specially designed for the use in control systems for milita...
