Axial-Lead Wirewound Resistors offer Surge Protection to 106.5J
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.
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).
The compact resistors provide high power ratings from 3W to 13W at +25 degrees C and 2,000-hour load-life stability of less than ± 3% at +25 degrees C. The devices offer resistances from 2 Ω to 938kΩ, with tolerances of ± 5% and ± 10%, and TCR of ± 50 ppm/ degree C for resistance from 2.0Ω to 9.9Ω, and ± 30 ppm/ degree C for resistance of 10Ω and above.
The CW - High Energy series is available with both lead (Pb)-free and tin/lead terminations. Samples and production quantities of the CW - High Energy series are available now, with a lead time of six to seven weeks for larger orders. Pricing for U.S. delivery only starts at $0.36 per piece.
