Thin Film Chip Resistors feature tolerances to 0.1%.November 15, 2012 -
Built using moisture-resistant tantalum nitride resistive film technology, E/H (Ta2N) QPL Resistors feature MIL-PRF-55342 listing, reliability M failure rate of 100 ppm, and TCR of 25 ppm/°C. Surface mount units offer power ratings from 50–1,000 mW, working voltages from 40–200 V, and resistance ranges from 49.9 Ω to 3.3 MΩ, depending on tolerance. For operating conditions up to +150°C, wraparound terminations have tenacious adhesion layer covered with electroplated nickel barrier layer.

Vishay Intertechnology Launches New QPL Tantalum Nitride Thin Film Chip Resistors for Military and Aerospace Applications
Devices Feature Tolerances to 0.1 % and TCR of 25 ppm/°C
MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today launched a new surface-mount chip resistor with a QPL MIL-PRF-55342 listing and an established reliability "M" failure rate of 100 ppm. Built using a moisture-resistant tantalum nitride resistive film technology, the new E/H (Ta2N) QPL resistors offer enhanced specifications for military and aerospace applications, including tolerances to 0.1 % and a TCR of 25 ppm/°C.
The E/H (Ta2N) QPL resistors are intended for use in control systems for military and aerospace applications where moisture during operation or long-term storage may be a concern. The devices' tantalum nitride resistive film assures a moisture resistance level that exceeds MIL-PRF-55342 limits by a factor of 50.
The E/H (Ta2N) MIL-PRF-55342 thin film resistors feature very low noise of less than - 25 dB and a low voltage coefficient of 0.5 ppm/V. Their wraparound terminations feature a tenacious adhesion layer covered with an electroplated nickel barrier layer for + 150 °C operating conditions and contribute resistance of less than 0.010 Ω typical.
The new resistors are offered in M55342 case sizes from 01 to 12, with power ratings from 50 mW to 1000 mW, working voltages from 40 V to 200 V, and resistance ranges from 49.9 Ω to 3.3 MΩ depending on tolerance.
Production quantities of the E/H (Ta2N) MIL-PRF-55342 thin film resistors are available now, with lead times of 8 to 10 weeks. Pricing for U.S. delivery is $0.45 to $2.00 and depends on case size and tolerance. Follow QPL/MIL resistors from Vishay at http://twitter.com/vishayindust.
