## Calculator of maximum power loss from thermal resistance

If thermal resistance is known for given device and cooling conditions then a maximum loss dissipation can be calculated from the following equation.

 $$P_{max} = \frac{T_{max} - T_{ambient}}{R_{th}}$$ (W)

Tmax (°C) =       Tambient (°C) =       Rth (°C/W) =

Pmax (W) =

Note: the maximum temperature must be greater than the ambient value.
