The FHR Series Resistors must be attached to a suitable heat-
sink. The maximum internal resistor temperature is 130°C.
To specify an appropriate heatsink use the following formula :
0.5%
0.2%
0.1%
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 )
