Tgard 20

Tgard 20 Series

Low Cost, Medium Performance Insulator Material

The Tgard 20 is designed to solve over heating issues such as lower component

efficiency, premature component failures, size limitations and other performance
problems for today’s computer power supplies.

The Tgard 20 is a film-based product designed to resist cut through in sc rew
mounting applications while providing a more consistent breakdown voltage over other
insulator constructions.

The phase change coating on the film core provides an excellent mating surface for low
pressure clip mounting applications.

• Reinforced with moderate temperature resistant film

• High voltage resistant film

• Total thermal resistance of 3.4°C/watt on TO-220

• Non-blocking for ease of use

• Designed for computer power supplies
