MALVERN, PENNSYLVANIA— Jan. 27, 2011— Vishay Intertechnology, Inc. (VSH: NYSE) today introduced the newPHPseries 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 industrial, telecommunications, and test and measurement instrumentation and equipment.
Featuring a high-purity ceramic substrate, thePHPseries 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 users’ circuit board.
Offered in the 1206 and 2512 case sizes, thePHPseries offers a resistance range from 10Ω to 30 kΩ, 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< - 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 to UL 94 V-0.
Samples and production quantities of thePHPseries will be available in Q1 2011, with lead times of 10 to 12 weeks for standard orders.
