Thermally Conductive Insulators
HIGH THERMAL AND DIELECTRIC PERFORMANCE INSULATOR PAD
Laird Tgard K52 is a high thermal and dielectric performance insulator pad consisting of a
ceramic filled phase change compound coated on MT Kapton film.
Laird Tgard K52 phase change coating all but eliminates contact thermal resistance. The phase
change coating melts at 52°C and replaces all contact areas that contain air. Tgard TM K52-1
is ideal for applications requiring the best thermal performing insulator material.
Laird Tgard K52-2 has the best balance of thermal, dielectric and cut through performance.
Laird Tgard K52-3 is a 3 mil PI film that provides the best crush, 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 VAC
• Resistant to tears and cut through
• Total thermal resistance of
0.13 - 0.30°C-in2/watt at 20 psi clip
• Audio amps
• Power modules
• Switching mode power supplies
Converting PARTS: Sheets and stand die cut availability for TO-220, TO-247, TO-3P, TO-3PL, and TO-264
CUSTOM DIE CUT PARTS: Custom configurations available with standard tolerance of 0.5mm (0.020”).
Ability to handle drawings in multiple file formats. (.DXF and .DWG preferred)
PRESSURE SENSITIVE ADHESIVE: Single side adhesive available on request with “A1 “suffix. Please
note this adhesive is intended to be a mounting aid and not for permanent bonding. A slight increase in
thermal resistance may be seen in comparison to material with no adhesive.
