Flexible Absorbent Material

(FAM)

 

    

FAM is a thin and flexible material, include soft rubber type and flexible sintered ferrite sheet with higher permeability. It can be cut any shape easily, freely arranged in space and provide effective EMI suppression in a wide frequency range (1MHz to 18GHz). Also can be a solution for RFID (Radio Frequency Identification) system on metal. It suitable for LF(125/134.2KHz) and HF(13.56MHz) bands on metal environment. It also works well in NFC (Near Field Communication)  technology application and Wireless Charger (WPC/Qi).
