Power Rating Notes The PFS35 Series Resistors must be attached to a suitable heatsink. The maximum internal resistor temperature is 175°C. To specify an appropriate heatsink use the following formula :
=
TMAX
- (P
- RHR)
- TA P
Where:Rq H = Thermal Resistance of Heatsink ( K/W ) Rq R = Thermal Resistance of Resistor ( K/W ) TMAX = Maximum Temperature of Resistor TA = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W )
