T69-70 is a high performing thermal interface material which is very thin, synthetically made from a highly oriented graphite polymer film and has excellent thermal properties in all axes. T69-70 is ideal for providing thermal management in some of the most demanding of applications.

FEATURES

  • Highly oriented pyrolytic graphite sheet with high thermal conductivity
  • It is flexible and has features of ultra-thin and high EMI shielding effect
  • Excellent thermal conductivity: 1600 W/ mK (4 times as high as copper, 7 times as high as aluminium)
  • Light weight: Specific gravity: 2.3
  • Flexible and easy to be cut or trimmed
  • Low thermal resistance
  • Low moisture content: < 1%

APPLICATIONS

  • Electronic components: IC, CPU, MOS
  • LED, M/B, P/S, Heat Sink
  • LCD, TV, Notebook PC, PC Telecom Device, Wireless, etc.
  • DDR II Module, DVD Applications, Hand-set applications, etc.
