Additional Information
This product is designed for use with proper heatsinking. The maximum base plate temperature must be monitored and kept within specified limits to ensure optimal performance. Attach a thermocouple to the side of the resistor's base plate for accurate temperature monitoring. The plastic housing or heat sink temperature cannot be used to establish the resistor's power rating.
