TFO-L-SI Silikonfolie glasfaserverstärkt

TFO-L-SI is an electrically insulating thermally conductive silicone foil for an optimised thermal coupling between electronic packages and heat sinks. Through the specific formulation and filling with thermally conductive ceramic particles a high thermal conductivity is reached. Its conformal surface structure guarantees a very good compliance to the contact surfaces even at low pressure. Thus the total thermal resistance is minimised. The material can be applied in a broad field of applications.
