Maximum working temperature must not exceed 175 °C. The dissipated power is simply calculated by the following ratio: (1) ΔT P = ----------------------------------------------------------------------------------[ R TH (j - c) ] + [ R TH (c - h) ] + [ R TH (h - a) ] P: Expressed in W ΔT: Difference between maximum working temperature and room temperature RTH (j - c): Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component. RTH (c - h): Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device. RTH (h - a): Thermal resistance of the heatsink. Example: RTH (c - h) + RTH (h - a) for LTO 100 H power rating 10 W at ambient temperature +25 °C Thermal resistance RTH (j - c): 1.5 °C/W Considering equation (1) we have: ΔT = 175 °C - 25 °C = 150 °C 150 ΔT RTH (j - c) + RTH (c - h) + RTH (h - a) = ------- = ----------- = 15 °C/W 10 P RTH (c - h) + RTH (h - a) = 15 °C/W - 1.5 °C/W = 13.5 °C/W with a thermal grease RTH (c - h) = 1 °C/W, we need a heatsink with RTH (h - a) = 12.5 °C/W.
