Flexible sheets from TDK solves magnetic interference problems in NFC

In today's high-reliable compact electronics systems with inductors coils featuring high magnetic flux density interfere with other electronic systems and also get interfered. In order to localise magnetic flux only at the source and not to get interfered by other sources, magnetic protection sheets are used to shield from interference. The leading passive electronic component manufacturer TDK has launched high permeability ultra-thin magnetic sheets for RF circuits integrated electronics applications such as near field communication (NFC) based RFID systems. By effectively using this material NFC RFID systems can effectively increase the communication range by solving tuning issues between the two antennas and optimum 13.56 MHz communication conditions can be maintained.
Since NFC based RFID basically works through induction, to ensure a reliable operation of NFC communication, the magnetics around NFC subsystem need to be designed for interference free communications. Any metal objects nearby can be shielded by placing the magnetic sheet in such a way that magnetic flux is confined within its influence area. The product named as IFQ06 material provides highly effective protection against external RF interference for the wrapped part of the system. Although NFC is an ...
