The dissipated power is simply calculated by the following ratio: 1 T P = ------------------------------------------------------------------------------------------R TH (j - c) + R TH (c - h) + R TH (h - a) P: T: RTH (j - c): RTH (c - h): RTH (h - a): Expressed in W  Difference between maximum working temperature and room temperature  Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component: (Special Features Table)  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 Thermal resistance of the heatsink Example:  RTH (c - a): For RTO 50 power rating 13 W at ambient temperature +30 °C Thermal resistance RTH (j - c): 2.6 °C/W Considering equation (1) we have: T  155 °C - 30 °C = 125 °C T P 125 13 RTH (j - c) + RTH (c - h) + RTH (h - a) = ------- = -------- = 9.6 °C/W RTH (c - a) + RTH (h - a)  9 .6 °C/W - 2.6 °C/W  7 °C/W Revision: 17-Oct-2018 Document Number: 50035 2 For technical questions, contact: sferfixedresistors@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
