Tgard™ 500 is a medium thermal performance insulator pad consisting of a ceramic filled high temperature silicone rubber coated on electrical grade fiberglass.
Tgard 500 is designed for applications that require additional thickness to prevent electrical shorts form stamped aluminum heatsinks used in switching mode power supplies (SMPS) and debris from aluminum castings used in automotive motor controls.
Features and benefits:
- High breakdown voltage of > 6,000 volts AC
- Thick enough to encapsulate burrs of stamped heatskinks
Applications:
- Switch mode power supplies
- Motor controllers
Manufacturer: Laird
