TgardTM 300 Series Thermally Conductive Insulators HIGH PERFORMANCE THERMAL INTERFACE PRODUCTS TgardTM 300 is a medium thermal performance insulator pad consisting of a ceramic high temperature silcone rubber coated on electrical fiberglass. Tgard 300 is specifically designed for applications that require low component mounting forces. The unique formulation will enhance thermal performance which minimizes thermal resistance at low mounting forces. The uniqe coating formulation offers an excellent mating surface for low pressure clip mounting applications.
