Thermally Conductive Insulators
Tgard
TM
20
LOW COST, MEDIUM PERFORMANCE INSULATOR MATERIAL
The Tgard
TM
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
TM
20 is a film-based product designed to resist cut through in screw
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.
PERFORMANCE CAPABILITIES
• High dielectric breakdown of 9,000 volts
• Film base resistance cut through
• Thermal resistance of 0.60°C-in
2
/ watt @ 25 psi pressure
FEATURES AND BENEFITS

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
APPLICATIONS
• Switching mode power supplies for:
- Computers
- Consumer electronics
• UPS units
