TTElectronics - Welwyn WHS54R7JT075 High Surge Resistor
The Welwyn WHS series are axial leaded wirewound high surge resistors designed for safety-critical applications. They feature an adjustable resistance range from 1 ohm to 330 ohms, based on E24 decade values. These UL-recognized, fuse-type resistors are suitable for line input circuits requiring reliable fusing in case of malfunction. They have a smaller form factor compared to uprated or multiple standard wirewound resistors. The series offers various isolation voltages (from 250V to 1000V) and power ratings from 2W to 10W at 25°C. Tolerance options include 1%, 2%, and 5%, with a resistance temperature coefficient of ±200ppm/°C. They operate over a wide ambient temperature range of -55°C to +155°C and support enhanced surge and pulse energy capacity. Available in radial taped, non-inductive, surface-mount ZI-form, and hot tin dipped copper wire configurations. Compliant with UL94-V0 flameproof standards and recognized by cURus.
