Power Rating Notes -
The PF2200 Series Thin Film Resistors must be attached to a
suitable heatsink. Without a heatsink the maximum power rating
is 1W ( 1/2W for the PF2201 ). The maximum internal resistor
temperature is 175°C.
To specify an appropriate heatsink use the following formula :
Where:

Mounting Notes -
The PF2200 Series Thin 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.
