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