TTElectronics - Welwyn WHS2220RJA25 High Surge Resistor
The Welwyn WHS series consists of axial leaded wirewound high surge resistors designed for safety-critical applications. These resistors feature a resistance range from 1 ohm to 330 ohms, covering E24 decade values. They are UL recognized wirewound fusible resistors, ideal for line input circuits requiring safe fusing in case of malfunction. The series offers reduced body size compared to standard or uprated wirewound resistors. Available with various isolation voltages ranging from 250V to 1000V, and power ratings from 2W to 10W at 25°C. They come in tolerances of 1%, 2%, and 5%, with a resistance temperature coefficient of ±200ppm/°C. The operating temperature range spans from -55°C to +155°C. Features include enhanced surge and pulse energy capacity, radial taped non-inductive versions, surface-mount ZI-form options, and hot tin-dipped copper wire construction. They are UL94-V0 flameproof and cURus recognized. Please note, market demand has extended lead times and delivery may fluctuate. Not eligible for discounts.
