Maximum working temperature must not exceed 175 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 the TH (j - c) component. R : Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the thermal resistance TH (c - h) of the interface (grease, thermal pad), and the quality of the fastening device. R : Thermal resistance of the heatsink TH (h - a) Example: R + R for LTO 150 power rating 10 W at ambient temperature +25 C TH (c - h) TH (h - a) Thermal resistance R : 0.87 C/W TH (j - c) (1) Considering equation we have: T = 175 C - 25 C = 150 C T 150 R + R + R = ------- = ----------- = 15 C/W TH (j - c) TH (c - h) TH (h - a) P 10 R + R = 15 C/W - 0.87 C/W = 14.13 C/W TH (c - h) TH (h - a) Example with a thermal grease R = 0.5 C/W, we need a heatsink with R = 13.63 C/W TH (c - h) TH (h - a) Revision: 15-Feb-18 Document Number: 50071 2 For technical questions, contact: sferfixedresistors vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
