Developed for inrush control applications, such as power supplies, UPS, energy metering, and motor drives, TT’s WHS-UL resistors offer enhanced surge and pulse energy withstand capability.
“We are supporting our customers in the rapid achievement of their EMC and safety testing goals with this safety agency-accredited product,” says TT’s Brian Stephenson.
A UL1412-recognised fusible resistor (UL file E234469), the WHS-UL provides failsafe fusing at 120 / 240Vrms with a UL94-V0 flameproof coating. Available in 2, 3 and 5W sizes and at E24 values from 10 to 100 ohms, these resistors offer up to 30J of surge energy capacity and as much as 7kV peak 1.2/50µs performance.
They also guarantee safe fusing in fault condition overloads from as low as 30W. The WHS-UL is available in a wide range of lead preforms, including vertical radial form in tape and ZI form for SMD processing
