Power Rating Notes -
°C
The PFC Series Resistors must be attached to a suitable heat-
sink. The maximum internal resistor temperature is 155°C.
To specify an appropriate heatsink use the following formula :
TMAX - (P * RHR) - TA
RHH =
P
°C
Where: RθH = Thermal Resistance of Heatsink ( K/W )
RθR = Thermal Resistance of Resistor ( K/W )
TMAX = Maximum Temperature of Resistor
TA = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )
Heatsink Temperature (°C)
Copper Insert
Copper insert improves thermal conductivity to heatsink. Power ratings
of 35W 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.
