Vishay Intertechnology Enhances E/H Series MIL-PRF-55342-Qualified Thin Film Resistors With “T” Level Failure Rate
MALVERN, Pa. — Feb. 3, 2015 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has enhanced its E/H series of precision MIL-PRF-55342-qualified thin film surface-mount resistor chips to offer a “T” level failure rate for critical space applications. The QPL devices are qualified to TCR characteristics E, H, K, L, and M in 12 case sizes.
The established reliability of the Vishay Dale Thin Film resistors is assured through 100 % screening and extensive environmental testing that includes complete 100 % Group A power conditioning and Group B lot testing, through which the devices have been rated and approved for a "T" failure rate level. In addition, the thin film resistors meet the ASTM-E595 requirements for outgassing in a vacuum environment.
Intended for satellite and communication applications with stringent performance requirements, the E/H series' all-sputtered wraparound terminations provide excellent adhesion and dimensional uniformity. The devices feature an electroplated nickel barrier layer for operating conditions to +150 °C, a TAMELOX resistive element, and a high-purity alumina substrate for high power ratings to 1000 mW.
In addition to very low noise of less than −25 dB and a low voltage coefficient of < 0.1 ppm/V, E/H series resistors offer an absolute TCR down to ± 25 ppm/°C, laser-trimmed tolerances down to ± 0.1 %, and a wide resistance range from 10 Ω to 6.19 MΩ, depending on case size and TCR characteristics. The devices provide a shelf-life stability of ± 0.01 % and are offered in antistatic waffle pack or tape-and-reel packaging.
