HSA25150RJ is an aluminium housed wire wound power resistor from the TE Connectivity HS Series, designed for high-power dissipation applications. It features a 25W power rating with heatsink (12.5W without heatsink), a 150O resistance value with ±5% tolerance, and operates over a temperature range of -55°C to 200°C. The resistor offers a maximum working voltage of 500V (DC or AC rms), isolation voltage of 2500V, and dielectric strength of 2500V AC peak. With its aluminium housing for efficient heat dissipation and 1% stability over 1000 hours, this resistor is ideal for braking, balancing, capacitor charging/discharging, crowbar, filter, and general electrical machinery applications.
