TgardTM 500 Thermally Conductive Insulators THICKER THERMAL INSULATOR PAD PREVENTS ELECTRICAL SHORTS IN AUTOMOTIVE ELECTRONICS APPLICATIONS TgardTM 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 tadditiional thickenss to prevent electrical shrots form stamped aluminumheatskinks used in switching mode power supplies (SMPS) and debris from aluminum castings used in automotive motor controls.
