MK3306/TG

## **Thermal Insulator Pad** 

## **Description** 

The product is a medium thermal performance insulator pad consisting of a ceramic filled high temperature silicone rubber coated on electrical grade fiberglass. 

The product is designed for applications that require additional thickness to prevent electrical shorts from stamped aluminium heatsinks used in switching mode power supplies (SMPS) and debris from aluminium castings used in automotive motor controls. 

Used in applications that require an interface of 2.5°C/watt or higher on a TO-220 mounted at 50 psi pressure.
