Maximum working temperature must not exceed 150 C. The dissipated power is simply calculated by the following ratio: ()1 T P = ------------------------------------------------------------------------------------------- R ++R R TH (j - c) TH (c - h) TH (h - a) P: expressed in W T: difference between maximum working temperature and room temperature R : thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of TH (j - c) the component. R : thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the TH (c - h) thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device. R : thermal resistance of the heatsink. TH (h - a) Example: R for LTO 30 power rating 10 W at ambient temperature +25 C TH (c - a) Thermal resistance R : 4.2 C/W TH (j - c) (1) Considering equation we have: T = 150 C - 25 C = 125 C T 125 R + R + R = ------- = -------- = 12.5 C/W TH (j - c) TH (c - h) TH (h - a) P 10 R R = 12.5 C/W - 4.2 C/W = 8.3 C/W TH (c - h) TH (h - a) with a thermal grease R = 1 C/W, we need a heatsink with R = 7.3 C/W.
