The maximum internal resistor temperature is 155°C. To specify an appropriate heatsink use the following formula : RqH = TMAX - ( P x RqR ) - TA P Where: R qH = Thermal Resistance of Heatsink ( K/W ) R qR = Thermal Resistance of Resistor ( K/W ) T MAX = Maximum Temperature of Resistor T A = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) Heatsink Temperature (°C) 0 25 50 75 100 125 150 175 200 100 120 Power ( % ) Power Derating Curve SPECIFICATIONS (continued) Copper insert improves thermal conductivity to heatsink. Power ratings of 25W can be achieved through active cooling of the heatsink. For more general information on heatsinking please see our training mod- ule on heatsinking by clicking here.
