Vishay Intertechnology (Malvern, PA) has launched 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 1,000 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, including tolerances to 0.1 % and TCR of 25 ppm/°C. The Vishay Dale Thin Film QPL resistors introduced today are intended for use in control systems for military and aerospace applications where moisture during operation or long-term storage may be a concern. Features include:

• Tantalum nitride resistive film assures a moisture resistance level that exceeds MIL-PRF-55342 limits by a factor of 50.
• Low noise of less than -25 dB and a low voltage coefficient of 0.5 ppm/V.
• A tenacious adhesion layer covered with an electroplated nickel barrier layer for +150 °C operating conditions.
• Resistance of less than 0.010 Ω typical.
