Vishay Intertechnology, Inc. today introduced a new series of silicone-coated axial lead wirewound resistors. Claiming superior short-term energy surge protection compared with standard wirewound devices, Vishay Dale CW – High Energy series resistors can also be utilized in high-temperature operating conditions up to +350 degrees C.
Recommended: SiC-based Three-Phase UPS is 98% Efficient
CW – High Energy resistors provide higher overload and high surge energy protection than traditional wirewound resistors, and they exceed IEC 61000-4-5 (1.2 µs/50 µs) requirements for communication equipment, 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).
