• 
• 

• 3M™ EMI Absorber AB13AL is a hybrid absorber that helps reduce the high frequency current that runs on the
  metal surface with high permeability, µ’=130, and good shielding effectiveness. It can help realize thin and smooth cable application.

• 3M™ EMI Absorber AB13AL (Hybrid) Key Features

  • Improve EMI Shielding performances with absorber layer
  • Improved read/write data error rates for data cable
  • Less EMI interference within a device
  • Multiple thickness options

  

3M™ Flux Field Directional Materials (FFDMs) for Wireless Power
Charger (WPC) application

• 

  Key Benefits of 3M FFDMs

  • Enhancement of wireless charging efficiency
  • Reduction of eddy currents on the conductor plate
  • Reliable, easy processing, thin, and high saturation level
  • Low eddy current loss at high frequencies
  • Wide frequency range: From kHz to MHz
    (Available for Qi-standard and A4WP requirements)

• Help increase of magnetic energy generated by coil/antenna using 3M FFDM with high permeability/low loss

  3M FFDMs can be optimized with the various type of magnetic materials and the internal performance test
