TDK Flexield Magnetic Shields For Near-Field Communications

TDK Flexields are thin, flexible magnetic sheets [shields] that have numerous applications within the electronics industry. For NFC shield applications, the magnetic parameters’ behavior over frequency greatly differs in importance than for other uses. This White Paper will explain key material characteristics quantified through figures of merit, which gives the designer a better understanding of how they impact read range performance and are supported by actual testing results. Additionally, a step-by-step check list is provided to ensure the designer considers all relevant system factors when doing their magnetic shield selection process.

Total Solutions for NFC Circuits

NFC stands for Near Field Communication, a type of short-range wireless communication.
Devices equipped with NFC can perform data transmission and authentication simply by being brought close to each other. This feature is rapidly being integrated into smartphones in recent times.
Additionally, its implementation is expanding to peripheral devices like wearable devices such as smartwatches.
NFC is widely used in cashless payment transactions and for connecting and authenticating peripheral devices. It holds the potential for diverse applications in realizing a touchless society.
This article introduces the main components used in NFC circuits, including NFC antennas, magnetic sheets, inductors for LC filters, and baluns for single-ended circuits.

TDK Product Features

The soft magnetic sheet material "Flexield" is an electromagnetic shield material made of magnetic materials and resin. It suppresses noise radiated from electronic devices across a wide frequency range. Because it is a sheet-type product with excellent flexibility in fabrication, mounting it on mobile devices such as notebook PCs, digital cameras, and cellular phones is easy. “Flexield” is lighter than the ferrite sintered body, with excellent shock-resistant properties. We can also offer a lineup of products that are even thinner and attain noise suppressing effects across a larger bandwidth because we have added metal layers. Furthermore, it is effective when mounting metal onto a reader/writer or tag of a RFID system for 13.56MHz band.
