Panasonic’s EYG-T series Graphite-PAD, one of its thermal management solutions, is a Thermal Interface Material (TIM) which offers excellent thermal conductivity in the Z-axis (thickness) direction and provides good flexibility. The new Graphite-PAD product’s performance is superior to that of most existing TIMs.

The Graphite-PAD product is composed of Pyrolytic Graphite Sheets (PGS) filler in silicone resin. This combination of materials offers high system reliability in designs with high heat dissipation. The PGS inside the resin is oriented in a vertical direction. This oriented structure provides excellent thermal conductivity through the thickness of the sheet.

Mainly composed of silicone resin, the thermal sheet is easily deformable, a property which eases installation.

The Graphite-PAD sheets are ideally suited to use in end products including:

  • Micro-inverters
  • IGBT modules and power transistors
  • Power converters
  • Radio devices
  • Touch panels
  • Cameras
  • Automotive LEDs
  • Motor-control units
  • Optical transceivers
  • 13W/mK thermal conductivity
  • Thickness range: 0.5mm to 3.0mm
  • Type E 25 hardness
  • 50% compressibility in 2mm thickness at 300kPa pressure
  • Operating-temperature range: -40°C to 150°C
  • Power supplies
  • Audio/visual equipment
  • Communications equipment
  • Medical equipment
