Power Rating Notes -
The FPR Series Resistors must be attached to a suitable heatsink. The maximum internal resistor temperature is 130°C.
To specify an appropriate heatsink use the following formula :
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 )
