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.
