TE Connectivity HS Series 300W 1R Wirewound Resistor

The TE Connectivity HS Series 300W 1R Resistor is a premium aluminium housed power resistor designed for demanding electrical applications. Its robust construction ensures exceptional stability and reliability, effectively dissipating up to 300W of power while maintaining a relatively low surface temperature. The resistor’s small footprint (43mm x 33mm x 15mm) allows for high power density in limited spaces, making it ideal for use in power supplies, power generation, and the traction industry.

Engineered with quality materials, this resistor rapidly transfers heat through its aluminium housing to an external heatsink, ensuring optimal performance and longevity. The 1 ohm resistance value and ±5% tolerance provide precise current control, while the threaded stud terminals facilitate secure panel mounting. With a working voltage rating of 2.5kV and a temperature coefficient of ±50ppm/°C, it delivers consistent operation across a wide temperature range (-55°C to +250°C).
