SZPH NFS40 series NFC ferrite sheet anti-metal sheet
Technical Specification
◆Material appearance and structure

◆Performance characteristics of NFS40 series
1.Improving the read and write failure of rf electronic product (such as the RFID electronic tag, antenna, reader and writer device, IC card,bus card) while encounter metal, play a role in metal interference, act best when the frequency is 13.56MHz;
2.High surface resistance can be used in more complex circuits;
3.High viscosity laminating effect leads to Higher reliability in application;
4.Passed ROHS and HFcertification, with flame retardant and aging characteristics
