# Heatsink Size Calculator

Introduction: Efficient cooling is vital for electronic components, and the Heatsink Size Calculator aids in determining the recommended heatsink size based on thermal power and thermal resistance. This ensures optimal temperature management for electronic devices.

Formula: The recommended heatsink size is calculated by multiplying the thermal power by the thermal resistance.

How to Use:

1. Enter the thermal power (in watts) in the first input field.
2. Enter the thermal resistance (in °C/W) in the second input field.
3. Click the “Calculate” button to obtain the recommended heatsink size.

Example: Suppose the thermal power is 10 watts, and the thermal resistance is 5 °C/W. Enter “10” in the first input field and “5” in the second input field. Click “Calculate,” and the result will provide the recommended heatsink size, which might be approximately 50 square centimeters.
