MALVERN, PENNSYLVANIA — September 22, 2004 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of its E/H MIL-qualified resistor chips in three new sizes - the compact 0402, 0603, and 0502 cases - that give designers greater flexibility in selecting devices for circuits requiring high-performing, high-precision, established-reliability resistors.

Intended for high-reliability military applications with stringent performance requirements, the new Vishay Thin Film resistor chips meet MIL-PRF-55342 specifications. Established reliability is assured through 100% screening and extensive lot testing, through which the new E/H devices have been rated for an "R" failure rate level.

These new resistors represent the industry's first established reliability resistors in standard package sizes with ratings from 100 ohms to 160 kilohms and an established reliability failure rate of 0.01% per 1000 hours. As a result, designers no longer need use commercial, non-qualified devices for applications requiring this combination of performance and size.

The devices' all-sputtered wraparound termination ensures excellent adhesion and dimensional uniformity. Exact dimensions and clean, straight edges are produced by a precise wafer-sawing process. The E/H resistors' electroplated nickel barrier layer enables operation at temperatures up to +150 °C, and their high-purity alumina substrate allows for high power ratings.

In addition to very low noise of less than -25 dB and a low voltage coefficient of ±0.5 ppm/V, the non-inductive E/H devices released today feature an absolute TCR down to ±25 ppm/°C, tolerances down to 0.1%, typical wraparound resistance of less than 0.010 ohms, and in-lot tracking of less than 5 ppm/°C.

Part Case Size Max. Working Voltage (V) Power Rating (mW) Characteristic Resistance Range (Ω)
E & H K (0.1%) (1%, 2%, 5%, 10%)
M55342/01 0502 40 10 20 100 - 130 K 59 - 130 K
M55342/11 0402 25 40 40 100 - 71.5 K 59 - 71.5 K
M55342/12 0603 50 70 70 100 - 160 K 20 - 160 K

E/H resistor chips feature a TAMELOX® resistive element with SPM (special passivation methods) and gold-over-nickel terminals. They are available in antistatic waffle pack or tape-and-reel packaging.

Samples and production quantities of the new devices are available now, with a lead time of stock to 10 weeks for larger orders.
