Maximum working temperature must not exceed 150 °C. The dissipated power is simply calculated by the following ratio: 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 - a): Thermal resistance value measured between outer side of the resistor and room temperature. It is the thermal resistance of the heatsink itself (type, shape) and the quality of the fastening device, and the thermal resistance of the thermal compound. Example: RTH (c - a) for LTO 50 power rating 10 W at ambient temperature + 25 °C Thermal resistance RTH (j - c): 2.5 °C/W Considering equation (1) we have: ΔT = 150 °C - 25 °C = 125 °C RTH (j - c) + RTH (c - a) = = = 12.5 °C/W RTH (c - a) = 12.5 °C/W - 2.5 °C/W = 10 °C/W with a thermal grease RTH (c - h) = 1 °C/W, we need a heatsink with RTH (h - a) = 9 °C/W.
