Vishay Intertechnology, Inc. today introduced a new series of silicone-coated axial lead wirewound resistors. Providing superior short-term surge protection compared with standard wirewound devices, Vishay Dale CW – High Surge series resistors combine high voltage surge immunity up to 12 kV with high-temperature operation to +350 degrees C in a high-reliability design.
Recommended: 25-mOhm / 1700-V SiC Transistors
CW – High Surge resistors provide overload and high surge voltage protection in accordance to IEC 61000-4-5 (1.2 µs/50 µs) requirements for power supplies, metering and welding equipment, power tools, and appliances in a wide range of applications. The devices offer a rugged, completely welded construction for increased reliability, while their high-temperature silicone coating allows for operating temperature ranges of -65 to +250 degrees C (characteristic U) and -65 to +350 degrees C (characteristic V).
