The NPR / NHR Series Resistors must be attached to a suitable
heatsink. The maximum internal resistor temperature is 155°C.
To specify an appropriate heatsink use the following formula :
RθH = TMAX - ( P x RθR ) - TA
P
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 )
