TTElectronics - Welwyn WHS21RJA25 High Surge Wirewound Resistor

The Welwyn WHS series consists of axial leaded wirewound resistors designed for high surge applications. They cover resistance values from 1 ohm to 330 ohms across E24 decade values. These UL-recognized wirewound fusible resistors are suitable for safety-critical line input circuits where reliable fusing is essential during malfunctions. They feature a reduced body size compared to standard or uprated wirewound resistors, with various voltage and power ratings depending on the model. The series includes options with isolation voltages ranging from 250V to 1000V, power ratings from 2W to 10W at 25°C, and tolerances of 1%, 2%, and 5%. They have a temperature coefficient of ±200 ppm/°C and operate effectively within -55°C to +155°C. Enhancements include higher surge and pulse energy capacity, surface-mount ZI-form options, and radial taped non-inductive types. The resistors use hot tin dipped copper wire, are flameproof (UL94-V0), and are cURus recognized.
