Vishay Intertechnology's New PHP Series of Precision High-Power Thin Film Chip Resistors Offers TCR to +/- 25 ppm/Deg. C, Tolerances to 0.1 %, and Power Ratings of 1 W in 1206 and 2.5 W in 2512 Case Sizes

MALVERN, PA--(Marketwire - January 27, 2011) - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the new PHP series of precision high-power thin film chip resistors. The devices feature a low absolute TCR of 25 ppm/°C, tolerances down to 0.1 %, and high power ratings from 1.0 to 2.5 W over a wide temperature range of - 55 °C to + 125 °C.

With stable film and performance characteristics of 1000 ppm at + 70 °C for 2000 hours, the devices released today are optimized for high-precision medical imaging and for industrial, telecommunications, and test and measurement instrumentation and equipment.

Featuring a high-purity ceramic substrate, the PHP series chip resistors are designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end user's circuit board.

Offered in the 1206 and 2512 case sizes, the PHP series offers a resistance range from 10 ohms to 30 kiliohms, with non-standard values available. The resistors feature 2x the power rating over traditional thin film chip resistors in the same case sizes, low noise of less than - 30 dB, low voltage coefficients of 0.1 ppm/V, and voltage ratings from 100 V to 200 V. Available with lead (Pb)-free or lead terminations, the devices are RoHS-compliant and flame-resistant in accordance with UL 94 V-0.

Samples and production quantities of the PHP series will be available in Q1 2011, with lead times of 10 to 12 weeks for standard orders. Follow Vishay thin film resistors at
