App description

Heat sink temperature calculator

Enter the value and click Calculate. The result will be displayed.

Input data:

Ambient temperature T_a max, unit: C

Junction temperature T_j max, unit: C

Resistance (thermal resistance) R, unit: C/Watt

Resistance R_a, unit: C/Watt

Resistance R_b, unit: C/Watt

Output data: junction temperature, unit: C; power, unit; Watt, BTU / Hour

Usage example

Ambient temperature T_a max: 28C

Junction temperature T_j max: 18C

Resistance (thermal resistance) R: 20C/Watt

Resistance R_a: 30C/Watt

Resistance R_b: 60C/Watt

Click "Calculate" output data at junction temperature: junction temperature: 28C
