Heatsink Thermal Resistance Budget Calculator
The thermal resistance budget of the radiator is evaluated according to the dissipative power, ambient temperature and upper limit of junction temperature.
Heatsink Thermal Resistance Budget Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- Compare the junction temperature and allowable thermal resistance of the candidate radiator at 10W dissipation.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Add the steady-state thermal resistance of the junction to the shell, shell to radiator, and radiator to the environment.
