MALVERN, PENNSYLVANIA — July 16, 2004 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of the PR series high-precision thin film resistor arrays in compact 1206, 0805, and 0603 case sizes with a low profile of just 0.4 mm. Vishay is the only manufacturer to offer 0.01% ratio tolerance as a standard product feature in such low-profile arrays.

Matched resistor networks in the PR series include from two to eight resistors and are precision-matched to 0.01% ratio tolerance - as opposed to a ratio tolerance of 0.05% in competing devices. The new resistor arrays serve as compact replacements for larger-package devices - those utilizing wirewound or hermetic packaging - in instrumentation amplifiers, precision voltage dividers, bridge network circuitry, and all other products requiring a matched pair or set of resistor elements.

The new devices feature a highly stable TAMELOX® (passivated nichrome) resistive layer. PR series resistor arrays are specified for anabsolute TCR (temperature coefficient ratio) of 10 ppm/°C and TCR tracking of 2 ppm/°C - or down to 1 ppm/°C on request. Very low noise of less than -30 dB and voltage coefficients of less than 0.1 ppm/V contribute to the excellent performance of these devices.

The Vishay Thin Film PR100 is packaged in a 1.6 mm-wide case with a 1 mm pitch. It is rated for a resistance range of 100 ohms to 200 kilohms and a working voltage of 35 V. In a 1.85 mm-wide case, the PR135 features a 1.35 mm pitch, a resistance range of 100 ohms to 300 kilohms, and a working voltage of 75 V. Finally, the PR182 occupies a 3 mm wide case with a 1.82 mm pitch and is rated for a resistance range of 100 ohms to 1 megohm and a working voltage of 100 V. All three products feature a power rating of 100 mW per resistor at +70 °C and an operating temperature range of -55 °C to +155 °C.

PR series high-precision resistor arrays feature pre-tinned terminations over a nickel barrier. They are available in waffle pack or tape-and-reel packaging.

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