Power Rating Notes -

% Power

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 :

+25 °C

100

T_MAX- (P * R_HR) - T_A

R_HH=

Where: R_qH= Thermal Resistance of Heatsink ( K/W )

R_qR= Thermal Resistance of Resistor ( K/W )

T_MAX= Maximum Temperature of Resistor

T_A= Ambient Temperature of Heatsink ( °C )

P = Power Through Resistor ( W )

Tenative continuous-pulse allowance at duty 0.01. Load life test will be necessary

in actual equipment, because curve may be changed by resistance, repetition, duty
