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 ). Torque termination screws to 5 in-lbs (0.6 N-m). Back plate is isolated from both pins.

The maximum internal resistor temperature is 155°C. To specify an appropriate heatsink use the following formula : RHH = TMAX - (P * RHR) - TA P Where: RθH = Thermal Resistance of Heatsink ( K/W ) RθR = Thermal Resistance of Resistor ( K/W ) TMAX = Maximum Temperature of Resistor TA = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) Riedon Inc. © Riedon, Inc.
