Electrically Insulating

Electrically Insulating

Tgard 3000


Tgard 3000 is specifically designed to solve overheating issues such as lower component efficiency, premature component failures, size limitations and other performance problems for today’s power component assemblies. The need to remove unwanted heat to ambient temperatures becomes more important as electronic systems pack more power into smaller spaces.

Tgard 3000 is a film-based product that is designed to resist cut through in screw mounting
applications while providing a more consistent breakdown voltage over other insulator constructions. The soft conformal coating on the film core provides an excellent mating surface for low pressure clip mounting applications

• Designed for switch mode power supply applications

• Reinforced with high temperature resistant film

• High voltage resistant film
