Mount resistor using thermal grease to a clean, fl at 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. PF2200 Series TO-220 Power Thin Film Resistors 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: R θH = Thermal Resistance of Heatsink ( °C/W ) R θR = Thermal Resistance of Resistor ( °C/W ) T MAX = Maximum Temperature of Resistor ( °C ) ( * )R P T P R T H MAX R A = - - H H mm tol.
