Where:
RqH = Thermal Resistance of Heatsink ( °C/W )
RqR = Thermal Resistance of Resistor ( °C/W )
TMAX = Maximum Temperature of Resistor
TA = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )
Mounting Notes The PF2200 Series Film Resistors must be attached to a suitable heatsink. Mount resistor using thermal grease to a clean,
flat surface. Use a compression washer to provide 150 to 300
pounds ( 665 to 1330N ) of mounting force. Torque mounting
screw to 8 in-lbs ( 0.9 N-m ).
Mounting tab is isolated from both pins.
