Mit thermal resistance
WebThermal resistance is the measure of the thermal performance of the device, expressed in °C/W in datasheets. The thermal conductivity of a semiconductor material is one of the parameters that defines the thermal resistance of each heat flow path. Thermal metrics are valuable inputs for increasing the thermal reliability of integrated circuits. WebHere we have taken into account one additional thermal resistance than in Section 17.2, the resistance due to convection on the interior, and include in our expression for heat transfer the bulk temperature of the fluid, , rather than the interior wall temperature, .
