Thermally Conductive Insulators
Tgard™ 5000 Series
THERMALLY CONDUCTIVE ELECTRICALLY INSULATIVE MATERIAL
Tgard™ 5000 is an excellent dielectric material with good thermal performance consisting of a
polyimide film coated with a ceramic-filled, high-temperature silicone rubber.
Tgard 5000 is ideal for applications that require a delta temperature across the interface of 2.0ºC/watt
or higher on a TO-220 clip mounted @ 50 psi pressure. Tgard 5000 has high dielectric strength for the
AC side of a switching mode power supply. Tgard 5000 is tough resulting in an exceptional cut-through
resistant material.
FEATURES AND BENEFITS
• High dielectric breakdown voltage of 6,000 volts
• Film base resistance cut through
• Thermal resistance of 0.40ºC-in2/watt @ 50 psi clip
pressure
• Thermal resistance of 0.23ºC-in2/watt @ 400 psi
screw pressure
APPLICATIONS
• Switching mode power supplies
• Electrial power generators
• UPS units
