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 mount- ing screw to 8 in-lbs ( 0.9 N-m ). Mounting tab is isolated from both pins.

Without a heatsink the maximum power rating is 1W ( 1/2W for the PF2201 ). The maximum internal resistor temperature is 155°C ( 120°C for the PF2201 ). To specify an appropriate heatsink use the following formula : Where: R qH = Thermal Resistance of Heatsink ( °C/W ) R qR = Thermal Resistance of Resistor ( °C/W ) T MAX = Maximum Temperature of Resistor ( °C ) T A = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) ( * )R P T P R T H MAX R A = - - H H
