Vishay Releases a New High-Reliability, Thick Film Resistor With Extremely Low Resistance Down to 10 mΩ, Tight Tolerances of ±1% and ±5%, and Low TCR Down to ±100 ppm/K
MALVERN, PENNSYLVANIA — March 7, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of a new thick film resistor that combines an extremely low resistance with tight tolerances and low TCR for current-sensing applications.
To provide high stability for current sensing and shunt applications in dc-to-dc converters, power supplies, motor circuits, computers, and cell phones, Vishay's CRCW....-EL thick film power resistor offers an extremely low resistance range from 10 mΩ to 100 mΩ, with tight tolerances of ±1 % and ±5 %.
The device is offered in three case sizes: the 0.1-W 0603, the 0.125-W 0805, and the 0.25-W 1206. The resistor features low TCR of ±100 ppm/K, ±200 ppm/K, ±300 ppm/K, ±400 ppm/K, and ±600 ppm/K over an operating temperature range of −55 °C to +155 °C.
The CRCW....-EL features a special metal glaze on high-quality ceramic with a protective overglaze. The RoHS-compliant resistor offers lead (Pb)-free solder contacts on a nickel barrier layer, with pure tin plating providing compatibility with both lead (Pb)-free and lead-containing soldering processes.
Samples and production quantities of the new thick film power resistor are available now, with lead times of six to eight weeks for larger orders.
