The maximum internal resistor temperature is 130°C. To specify an appropriate heatsink use the following formula : 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 ) ( * )R P T P R T H MAX R A = - - H H
