Thicker Thermal Insulator Pad Prevents Electrical Shorts In Automotive Electronics Applications

Tgard 500 is a medium thermal performance insulator pad consisting of a ceramic filled high
temperature silcone rubber coated on electrical grade fiberglass.

Tgard 500 is designed for applications that require traditional thickenss to prevent electrical shorts from stamped aluminum heatskinks used in switching mode power supplies (SMPS) and debris from aluminum castings used in automotive motor controls.
