Emasfalis® RFID&NFC Series RF Absorber

RFID&NFC series RF Absorber is an absorber based on soft magnetic material. Improves communication of RFID & NFC at 13.56MHz by reduce metal interference.

It has a high magnetic permeability for RFID (13.56MHz) antenna, and unlike sintered ferrite, the product made of highly flexible resin binder and soft magnetic powder has excellent workability and can be supplied in rolls. Is possible.

*Affected by application and usage such as noise attenuation, contact surface condition, material, and thickness. ‥

*In general, it is possible to increase the amount of noise attenuation by increasing the thickness of the noise suppression sheet.

RFID&NFC Series Overview

Overview	MINORU® The RF Absorber is made of high permeability soft magnetic material. It has high flexibility and strong impact absorption characteristics. RFID, NFC, etc. at 13.56MHz improve the reduction of communication distance due to metal interference.
Structure
Characteristic	High flexibility and high workability such as die cutting. Adhesive layer (optional) facilitates easy assembly. * Flexible design support is possible without the need for grounding.
Application	∗ RFID, NFC antenna (13.56MHz) measures against metal interference ∗ Communication quality can be improved by installing it between the antenna such as batteries, metal housing, board level shield (BLS) and PCB and the antenna.
