The maximum internal resistor temperature is 175°C. To specify an appropriate heatsink use the following formula : RqH = TMAX - ( P x RqR ) - TA P Where: RqH = Thermal Resistance of Heatsink ( K/W ) RqR = Thermal Resistance of Resistor ( K/W ) TMAX = Maximum Temperature of Resistor TA = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) 100 120 0 25 40 55 70 85 100 115 130 145 155 175 Temperature of the backplate (°C) Power (% from nominal power)
