Is lower heat sink thermal resistance better

Witryna15 lip 2011 · This thermal resistance is the sum of a few different thermal resistances which you normally (should) find in the datasheet: there's the junction-to-case resistance and the case-to-ambient resistance. The former is very low, because the heat transfer is through conduction, while the latter is a much higher value because here the heat … Witryna22 mar 2024 · Any heat sink should be mounted to a component with a thermal pad or thermal paste. Both mounting techniques take advantage of the low thermal resistance of the heat sink and the pad/paste material. This aids heat conduction away from the component and into the heat sink, where heat can be dissipated into the surrounding …
