Tubes and sleeves are a ‘perfect fit’ for transistors, says Fujipoly

Tube-shaped thermal interface covers provide an easy way to improve transistor cooling while streamlining the manufacturing process, says Fujipoly.

The Sarcon tubes and sleeves are available in several standard sizes to fit many common transistor types and can be custom ordered to a customer’s exact specifications. Installation takes seconds and is a process of sliding the tube over the heat-generating component. Once fitted, unwanted heat is dissipated to the surrounding environment or nearby heatsinks.

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

Fujipoly America is a wholly owned subsidiary of Fuji Polymer Industries of Japan. It is an ISO9001:2015 registered company and specialises in the fabrication of silicone rubber technology, including Zebra elastomeric connectors, Sarcon thermal interface materials, fusible tapes and custom silicone rubber extrusions.

Fuji Polymer Industries has eight divisions worldwide, located in North America, Europe and Asia and an international network of distributors and representatives. The company’s North American operations are based in Carteret, New Jersey.
