HSA5056RJ is a 50-watt aluminium housed power resistor from the TE Connectivity HS Series, engineered for reliable high-power dissipation in compact form factors. The resistor delivers 50 watts dissipation at 25°C with a heatsink and 20 watts without, with a maximum working voltage of 1250 V (DC or AC rms) and an isolation voltage of 2500 V. It features an operating temperature range of -55°C to +200°C, resistance stability of ±1% over 1000 hours, and a standard heatsink area of 53,500 mm² with 1 mm thickness and 2 mounting holes. The device supports ohmic values from 0.01 O to 100 kO with standard ±5% tolerance, making it suitable for braking resistors, balancing resistors, capacitor charging/discharging, crowbar circuits, and general electrical machinery applications where reliable power dissipation and thermal stability are essential.
