Description
Tgard K52 is a high thermal and dielectric performance insulator pad consisting of a ceramic filled phase change compound coated on MT Kapton film. Tgard K52 phase change coating all but eliminates contact thermal resistance. The phase change coating melts at 52ºC and replaces all contact areas that contain air.
Tgard K52-1 is ideal for applications requiring the best thermal performing insulator material.
Benefits
- Tgard K52-2 has the best balance of thermal, dielectric and cut through performance.
- Tgard K52-3 is a 3 mil MT Kapton film that provides the best crush and cut and tear resistance available with thermal properties that are still in the high performance category.
Features
- High breakdown voltage of 4,000 – 9,000 range VAC
- Resistant to tears and cut through
- Total thermal resistance of 0.13 - 0.30 range ºC-in2/watt at 20 psi clip force
Recommended Uses
- Audio amp, Power modules, Switching mode power supplies.
