CHOICE OF THE HEATSINK
The user must choose according to the working conditions of the component (power, room temperature).
Maximum working temperature must not exceed 175 °C. The dissipated power is simply calculated by the following ratio:
Example:
R
Thermal resistance R
Considering equation (1) we have:

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.
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.
