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.

0.1%

To specify an appropriate heatsink use the following formula :

R_θH= T_MAX- ( P x R_θR) - T_A

Where:

_H= Thermal Resistance of Heatsink ( K/W )

_R= Thermal Resistance of Resistor ( K/W )
