Use Fourier’s law to examine the thermal path from a TO-220 power device through a silicone cap to a heatsink, with insulation and package-fit checkpoints.
A practical look at how thermal grease fills microscopic interface gaps and how the NIST steady-state resistance model connects thickness, heat flux, and temperature difference.
TO-220 packaged power components need both thermal management and electrical insulation. This article explains how a one-piece heat conductive silicone cap addresses both, and what to check when selecting a size.
