RFID/NFC Flexible Ferrite Sheet: FFSX Series

EMI flexible noise suppression ferrite sheet, engineered for both RFID/NFC and Rezence wireless charging

  • Thin, sintered ferrite with higher loss and more flexibility
  • Excellent performance in suppressing broadband noise
  • Effective for RFID/NFC-to-metal systems at 13.56MHz
  • Increases field strength from Tx to Rx for wireless charging (6.78MHz)
  • No fixture is necessary, adhesive on one side for easy mounting onto chip
