Kemet mats - overview

FLEX SUPPRESSOR® is a composite magnetic body in the form of sheet made by blending and dispersing micron sized magnetic material powders in a polymer base, and a sheet type noise suppressor effectively suppressing high frequency noise generated from electronic devices.



Structure





Specifications

  • High permeability
  • GHz Band High Performance
  • UL94 V-0


Applications

  • Radiation noise suppression in all kinds of electronic equipment
  • Measures for the desense LTE, Wi-Fi, GPS, etc.
  • Malfunction prevention of ESD
  • Magnetic material for Wireless Power Transfer

Features

  • Electromagnetic wave suppression – the electromagnetic wave enters through the sheet and is suppressed by losing its magnetic structure
  • Resonance suppression – controls the high frequency current and suppresses unwanted electromagnetic resonance by creating impedance
  • Wide range of frequencies available from MHz band to GHz band
  • Thin, flexible material used in portable equipment
  • Virtually no limitation to where it can be used
  • Less time required for installation
  • Easily cut into any shape
  • RoHS compliant and halogen-free
  • AEC-Q200 (FF1 and EFF4)
