WebThen with an accurate measurement of temperature at that point (Tx) the true thermal resistance can be calculated as: Rth (JX_Ө) = (Tj –Tx) / P. Where P is the dissipated power (heat) that flows from the junction to the point ‘X’. Ideally, during this measurement, close to 100% of the power should flow from the junction to the point ‘X’. http://coolinghouse.com/thermal-knowledge/thermal-resistance/
