The T-gardTM 3000 is a film-based product like thermal conductive tape, thermal conductive adhesive etc 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.

Features and Benefits:

• Designed for switch mode power supply applications
• Reinforced with high temperature resistant film
• High voltage resistant film
• Total thermal resistance of 2.2 °C/watt on TO-220
• Does not require powder to reduce surface tack
• Non-blocking for ease of use

Performance Capabilities:

• High dielectric breakdown of 6,000 volts
• Film base resistance cut through
• Thermal resistance of 0.45 °C-in2/watt @ 50 psi pressure
• Thermal resistance of 0.35 °C-in2/watt @ 400 psi pressure

Applications:

• Switching mode power supplies for:
• Communications
• Computers
• Consumer electronics
• Industrial
• Instrumentation
• Medical
• Electrical power generators
• UPS units
