[Under development] Noise suppression thermal conductive sheet Carbon fiber type

Thermal conductive sheet, just a single sheet of which is capable of both noise suppression and high thermal conductivity in vertical direction for heat dissipation

  • Product name
    EX10000K3 series
  • Features
    Capability of high suppression of GHz-band high frequency noise is attained through the mixing with magnetic powder. Moreover, the high thermal conductivity of 20 W/m·K in a vertical direction makes it suitable for heat dissipation and noise suppression for LSIs handling high-speed, large-capacity data processing, such as those required for 5G communication.
