TTElectronics - Welwyn WHS31RJA1 High Surge Resistor

The Welwyn WHS series are axial leaded wirewound high surge resistors with a resistance range from 1 ohm to 330 ohms, covering E24 decade values. These UL-recognized, wirewound fusible resistors are designed for safety-critical applications, especially in line input circuits where reliable fusing is essential. They feature a reduced body size compared to traditional or multiple standard wirewound resistors. The series offers various isolation voltages, such as 250V, 350V, 500V, 700V, and 1000V, depending on the model. Power ratings at 25°C range from 2W to 10W. They are available in tolerances of 1%, 2%, and 5%, with a temperature coefficient of ±200ppm/°C. The resistors operate over an ambient temperature range of -55°C to +155°C, with enhanced surge and pulse energy capacity. They have a radial taped form, with options for non-inductive types and surface-mount ZI-form. Made with hot tin-dipped copper wire, they are flameproof (UL94-V0) and recognized by cULus safety standards.
