Vishay's New Thin Film Chip Resistors, Aimed at Down-Hole Drilling and Aviation Applications, Feature 215 deg. C Maximum Operating Temperature, 25 ppm/deg. C TCR, and Tolerances Down to 0.05 %

MALVERN, PA--(Marketwire - April 15, 2010) -  A new series of wire-bondable, bare die chip resistors and resistor networks optimized for extreme high-temperature environments such as down-hole drilling and aviation applications was released today by Vishay Intertechnology, Inc. (NYSE: VSH).

The new Vishay Sfernice RMKHT wire-bondable chip resistors and resistor networks feature an operating temperature range from - 55 to + 215 deg. C, with a maximum storage temperature up to + 230 deg. C, an industry first for any resistor built on thin film technology. Even with this high temperature rating, the devices feature a load life stability of 0.5 % after 1,000 hours at 215 deg. C, as well as tight TCR and tolerance values.

Typical TCR for the new discrete resistors is 25 ppm/deg. C, with available tolerances down to 0.05 %. Typical tracking TCR for the resistor networks is 2 ppm/deg. C with a ratio tolerance as low as 0.02 %.

The RMKHT resistors and resistor networks, which have a 0.4-mm height profile, are available in footprint options from 20 mils by 20 mils to 100 mils by 200 mils and with an ohmic range of 10 ohms to 6 megohms, depending on series. Their power ratings range from 5 mW to 100 mW or 10 mW per resistor element for the resistor networks.

The RMKHT devices feature a wire-bondable construction with aluminum pads and a metallized backside option. Custom versions (CNHT) of the devices are available on request.

Samples and production quantities of Vishay's new RMKHT resistors and resistor networks are available now, with lead times of 10 to 12 weeks for larger orders. Follow Vishay products for down-hole drilling applications at http://twitter.com/VishayIndust.
