Thermal Resistance Calculator for Android
Thermal resistance is a critical factor in Android device design, ensuring optimal performance and longevity. Our calculator helps you determine the thermal resistance required for your device, considering power, ambient temperature, and case material.
How to Use This Calculator
- Enter the power consumption of your Android device in watts.
- Enter the ambient temperature in degrees Celsius.
- Select the case material from the dropdown menu.
- Click the ‘Calculate’ button.
Formula & Methodology
The thermal resistance (Rth) is calculated using the formula:
Rth = (P / (Tj – Ta)) / A
Where:
- P is the power consumption in watts.
- Tj is the junction temperature in degrees Celsius.
- Ta is the ambient temperature in degrees Celsius.
- A is the surface area of the device in square meters.
