Fujipoly tube-shaped thermal interface covers provide an easy way to improve transistor cooling while streamlining manufacturing processes. Sarcon tubes and sleeves are available in several standard sizes to Source: Fujipolyfit many common transistor types and can be custom ordered to the user's exact specifications. Installation takes seconds by sliding the tube over the heat-generating component. Once fitted, unwanted heat is dissipated to the surrounding environment or nearby heatsinks.

Depending on an application’s power and cooling requirements, Fujipoly tube-shaped covers are offered in several Sarcon formulations with thicknesses ranging from 0.30 mm to 0.85 mm. Thermal conductivity ranges from 1.2 to 2.2 W/m•K. Each tube-shaped cover provides additional benefits including electrical insulation and vibration/impact protection.
