Short Time Overload: 2x rated power for 5 seconds, resistance change within ±0.3%
Additional Information
This product is designed for use with proper heatsinking. The maximum base plate temperature must be monitored to ensure safe operation. It is recommended to attach a thermocouple to the side of the base plate to accurately measure temperature. The plastic housing or heat sink temperature alone cannot be used to determine the resistor's rating.
For detailed specifications, please refer to the datasheet.
