TTElectronics - Welwyn WHS3330RJA1 Wirewound Surge Resistors

The Welwyn WHS series are axial leaded wirewound high surge resistors designed for safety-critical applications. They feature resistance values from 1 ohm to 330 ohms within the E24 decade, with various voltage isolations ranging from 250V to 1000V depending on the model. These resistors are UL recognized and serve as wirewound fusible safety components in line input circuits, providing reliable fusing in case of malfunction. They offer power ratings from 2W to 10W at 25°C, with available tolerances of 1%, 2%, and 5%. The resistors are built with a hot tin dipped copper wire, have a temperature coefficient of ±200ppm/°C, and operate within an ambient temperature range of -55°C to +155°C. They feature enhanced surge and pulse energy capacity, and are available in radial taped, non-inductive, and surface-mount ZI-form options, with UL94-V0 flameproof protection and cURus recognition.
