Tgard 300

Thermally Conductive Insulator

Product Description

Tgard 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.

Features and Benefits
  • Unique coating formulation offers low mounting forces
  • High breakdown voltage
