  • Microwave absorber sheet for NFC
  • Microwave absorber sheet for NFC replacing ferrite sheet
  • Noise suppressing magnetic sheet for NFC

Overview

  • Magnetic sheets for NFC/RFID are electromagnetic shield materials that can improve data communications and authentication when two NFC-compatible devices are brought close together.
  • Magentic sheet of high permeability and resistance is placed between the metal and the antenna to eliminate Eddy Currents* generated in the metal in contact with the NFC antenna.
  • Noise suppression magnetic sheet for NFC/RFID is suitable for Near Field Communication (NFC), Wireless Power Charger (WPC), and Magnetic Security Transmission (MST).
  • Aavailable both in roll form and in sheet form

* Eddy Currents are generated by the metal in contact with the NFC antenna, and it causes the inductance of the antenna coil to be lowered, resulting in communication failure.

Features

  • Suitable for NFC, WPC, and MST
  • Ultra-thin flexible electromagnetic wave absorbing sheet (It can be made up to thickness 30㎛ ~ 500㎛)
  • Non-electrical conductivity
  • Easy to attach the tape to the surface of the flexible absorbing sheet
  • Manufactured in roll or sheet type and can be processed into various shapes depending on the application.
  • It can be used as a ferrite sheet.
