The HSA50R62J is a high-quality, aluminium-housed power resistor from the HS Series. It is designed to dissipate 50W of power when mounted on a heatsink and 20W without one. This model features a resistance of 0.62 ohms with a ±5% tolerance. Key electrical characteristics include a maximum working voltage of 1250V, a dielectric strength of 2500V AC peak, and an operating temperature range of -55°C to 200°C. Its stable, reliable performance makes it suitable for demanding applications such as braking resistors, capacitor charging/discharging, and filters in electrical machinery.
