5780 EMI Flexible absorber sheets

The EMI flexible absorber sheets developed for electromagnetic wave absorber and noise suppression can eliminate noise effectively

The EMI flexible absorber sheets developed for electromagnetic wave absorber and noise suppression can eliminate noise effectively. You can solve EMC/EMI problems by attaching noise suppression sheets simply on the parts of noise sources.


Features and benefits

  • Very flexible and easy to handle
  • Can be deliverd in any shape, size and/or thickness
  • Optionally available as custom made tube
  • Can be cut according to your supplied drawings
  • Provide effective EMI suppression in a wide frequency range (10MHz to 18GHz)
  • Change the magnetic flux path to avoid interference on other components or surrounding cables
  • Reduce the eddy current when the magnetic flux is close to metal
  • Non-conductive adhesive backing (UL Recognized)
    available
  • Effective in preventing resonance and suppressing coupling
  • High surface resistance (>106 ohms)
  • Easy and fast to process through self adhesive

Effect diagram - Magnetic shield

5780-Effect-Diagram-magnetic-shield

5780 EMI Flexible absorber sheets can change the magnetic flux path to avoid the magnetic flux affect others components.

Effect diagram - RFID/NFC on metal

5780-Effect-Diagram-RFID-NFC-on-metal

The magnetic flux induced eddy current and generated a reverse magnetic field to offset the
magnetic flux to cancel the communication. After attached 5780 between metal and RFID
antenna, the communication will recover.

Effect diagram - Wireless Power Charger

5780 EMI Flexible absorber sheets can be used for wireless power charger to avoid eddy current when RX coil attached on
metal and change the magnetic flux path between TX coil, RX coil, magnet.
