Vishay RLR and RNR military qualified metal film resistors now available from TTI

Two new series of Vishay metal film resistors which are qualified to military standards are now available from TTI Inc. Vishay is seen as a leader in thin film technology and its RLR metal film resistors meet the requirements of MIL-PRF-39017 and suit satellite and GPS systems, while the RNR series is qualified and compliant with MIL-PRF-55182 (type RNR/RNN) and suits airborne systems.

The Vishay RLR Series has an epoxy coated construction which provides enhanced protection against moisture. Operating temperature range is -65degC to +150degC. TTI has parts in stock at non-precision tolerances of ±1 % or ±2 %. Standard electrical specifications include: maximum working voltage of between 200V and 500V depending on model selected, and power rating at 70degC of between 0.125W and 1.0W again depending on model. There is an extended value range up to 22 MO available from various DSCC drawings on request.

Vishay RNR series metal film resistors feature hermetic glass enclosures that are impervious to corrosive environments and atmospheres, suiting them to diverse mil/aero applications including airborne systems. They are very low noise (- 40 dB). The parts have established reliability rates and are subject to on-going quality maintenance programmes.
