## **HIGH THERMAL AND DIELECTRIC PERFORMANCE INSULATOR PAD** 

Tgard[TM] K52 is a high thermal and dielectric performance insulator pad consisting of a ceramic filled phase change compound coated on MT Kapton film. 

Tgard[TM] 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[TM] K52-1 is ideal for applications requiring the best thermal performing insulator material. 

Tgard[TM] K52-2 has the best balance of thermal, dielectric and cut through performance. Tgard[TM] 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 AND BENEFITS** 

- 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 

## **APPLICATIONS** 

- Audio amps 

- Power modules 

- Switching mode power supplies
