The maximum internal resistor temperature is 130C. To specify an appropriate heatsink use the following formula : T -(P*R )-T MAX HR A R = HH P Where: R = Thermal Resistance of Heatsink ( K/W ) qH R = Thermal Resistance of Resistor ( K/W ) qR T = Maximum Temperature of Resistor MAX T = Ambient Temperature of Heatsink ( C ) A P = Power Through Resistor ( W ) Riedon Inc. 300 Cypress Avenue Alhambra CA 91801 (626) 284-9901 (626) 284-1704 Riedon, Inc.
