LAIRD TFLEX 670

Main features

  • 0.070-Inch Gap-Filler Format
  • Electrically Insulating Thermal Interface
  • Compliant Adhesive-Free Interface Placement

Product Description

Tflex 670 uses a nominal 0.070 in ceramic-filled silicone sheet to fill thermal gaps in electronic assemblies. Within the Tflex 600 family, typical thermal conductivity is 3.0 W/(m K) and Shore 00 hardness is 51. Its highly compliant construction is suited to low-stress interfaces, and the naturally tacky surface requires no added adhesive coating. The sheet is electrically insulating and has typical volume resistivity of 2 x 10^13 ohm cm. Applications include automotive ADAS, automotive electronics, drones and satellites, gaming systems, instrumentation, portable devices, routers, and wireless infrastructure.

Key features

  • Nominal 0.070 in sheet: The exact thickness-coded grade supplies a 0.070 in Tflex 600 format.
  • Electrical interface insulation: Typical volume resistivity is 2 x 10^13 ohm cm by ASTM D257.
  • Compliant natural tack: The low-stress interface pad requires no additional adhesive coating.

Applications

Automotive ADAS; automotive electronics; drones and satellites; gaming systems; instrumentation; notebooks, tablets, and portable devices; wireless infrastructure.
