Noise Suppression Sheets (Shield)
Tech Notes
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.

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.
FPC is a homogeneous mixture of ferrite powder and plastic with outstanding mechanical and magnetic properties.
This rugged material can be processed into injection-molded parts or thin, flexible film to open up innovative applications.
