SAMPLE ORDER

TCP-C-SI is a thermally conductive silicone cap for an optimised thermal coupling between electronic packages and heat sinks which provides for a reliable electrical all-around insulation. Through the specific formulation and filling with thermally conductive ceramic particles a good thermal conductivity is reached. Its conformal surface structure guarantees a very good compliance to the contact surfaces. Thus the total thermal resistance is minimised.

PROPERTIES

Very good surface compliance
High thermal contact
Extraordinary chemical resistance and longterm stability
Residue-free removal after use

AVAILABILITY

Thicknesses: 0.5 mm and 0.8 mm
Different sizes available

APPLICATION EXAMPLES

Thermal link of:

MOSFETs or IGBTs
Power diodes or AC/DC converters

For use in Switch mode power supplies / Motor control units / Automotive engine management systems / UPS units / Solar systems
