Our Wirewound High Power Rating Resistors or RWH series have high power rating of up to 15 watts, and these resistors contains silicone coating that provides protection against high temperatures. These axial leaded resistors also feature excellent pulse handling, a temperature coefficient of as low as ± 20ppm/°C, and a complete welded construction. Additionally, the RWH series are capable of sustaining extreme voltage fluctuations making them well suited for industrial applications such as motor control, and medical applications such as MRI’s.
