The maximum internal resistor temperature is 175C. To specify an appropriate heatsink use the following formula : 80 60 R = T - ( P x R ) - T H MAX R A P 40 20 Where: R = Thermal Resistance of Heatsink ( K/W ) H R = Thermal Resistance of Resistor ( K/W ) R 0 T = Maximum Temperature of Resistor MAX T = Ambient Temperature of Heatsink ( C ) 0 25 40 55 70 85 100 115 130 145 155 175 A P = Power Through Resistor ( W ) Temperature of the backplate (C) Dimensions tol. tol.
