LAIRD TGON 805

Main features

  • 0.13 mm Flexible Graphite Interface
  • 5 W/(m K) Through-Plane Conductivity
  • 0.07 deg C in^2/W Thermal Resistance

Product Description

Laird Tgon™ 805 is the 0.13 mm-thick configuration of the Tgon™ 800 Series, a flexible graphite interface pad designed for applications where electrical isolation is not required and both electrical contact and thermal transfer are desired. Its grain-oriented, plate-like graphite structure provides typical thermal conductivity of 5 W/m·K through the Z axis and 240 W/m·K in the X-Y plane. The material contains more than 98% graphite and is available without adhesive or with a thin pressure-sensitive adhesive on one side to aid assembly.

Key Features

  • 0.13 mm nominal thickness for thin electrically and thermally conductive interfaces.
  • Anisotropic thermal conductivity of 5 W/m·K through-plane and 240 W/m·K in-plane.
  • More than 98% graphite construction with low thermal resistance and optional one-side pressure-sensitive adhesive.

Applications / Suitable for

  • Power conversion equipment
  • Power supplies
  • Large telecommunications switching hardware
  • Notebook computers
  • Applications requiring electrical grounding with thermal conductivity

Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
5 W/m.K
UL 94 Rating
Flammability rating classification. It determines how fast a material burns or extinguishes once it is ignited. HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed. V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole. 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole

Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
