The maximum internal resistor temperature is 155°C. +25 °C 100 To specify an appropriate heatsink use the following formula : Power (%) 80 60 PFC10 +155 °C 40 20 0 -50 0 50 100 150 Heatsink Temperature (°C) 200 RHH = TMAX - (P * RHR) - 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 ) Via-Holes Copper Insert Copper insert improves thermal conductivity to heatsink. Power ratings of 35 watts can be achieved through active cooling of the heatsink.
