Required sink
12 W with a 125 °C junction limit at 45 °C ambient allows 6.67 °C/W total; after junction-to-case and interface resistance, the sink must be about 4.7 °C/W or better.
How Калькулятор радиатора works
- Open Калькулятор радиатора and review the example state before entering your own values.
- Enter or select the information needed for Калькулятор радиатора.
- Review the result and adjust the inputs if you want to compare another case.
Work out the heat sink thermal resistance a component needs from its power dissipation, maximum junction temperature, and ambient conditions. The interactive workspace runs in your browser, so you can review the result without creating an account.
