The FPR/FNR Series Foil Resistors must be attached to a suit-
able heatsink. The maximum internal resistor temperature is
130°C for a 0.5% stability part.
To specify an appropriate heatsink use the following formula :
R θH = T MAX - ( P x R θR ) - T A

Where:
R θ H = Thermal Resistance of Heatsink ( K/W )
R θ R = Thermal Resistance of Resistor ( K/W )
T MAX = Maximum Temperature of Resistor
T A = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )
