To220 Heat Sink Calculator

The thermal resistance of the heat sink and temperature of the power source is calculated.

To220 heat sink calculator.

How does the heat sink calculator work. Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance. In our experience it generally estimates the overall heat sink volume within 15 of a final design.

Power components have a maximum junction temperature which must not be exceeded to prevent damage to the device.

A reference link has been placed below the calculator for further reading.

The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink. Heat sink temperature calculator. Devices are encapsulated in packages which have different levels of thermal resistance. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
