Flex Suppressor(R) Magnetic Sheet for RFID Overview Applications The KEMET Magnetic Sheet for radio frequency identification (RFID) Flex Suppressor(R) prevents interference between a loop antenna and metallic objects and effectively improves the communication range of RFID. * Cell phone with radio frequency identification (RFID) function * Contactless IC card * RFID reader/writer * RFID tag The flexible sheet is a polymer base, blended with micronsized magnetic powders dispersed throughout the material. These sheets improve the magnetic flux convergence and can be cut into a variety of shapes and sizes. Benefits * Magnetic flux convergence improvement - increases the relative permeability (u') while keeping the magnetic loss (u") low. * Effective carrier frequency 13.56 MHz and below * Resistant to shock, not brittle * Thin, flexible material used in portable equipment * Virtually no limitation in where it can be used * Less time required for installation * Easily cut into any shape * Easily laminates the Flex Suppressor(R) roll to the tag roll * RoHS compliant and halogen-free Sheet Type Roll Type One world.

Storage environment should be below 40C and below 70% relative humidity. The surface resistance value listed in this catalog is a reference value of the circuit parameter to indicate noise suppression. The value does not represent the product's insulation characteristics. The value may become lower if an excess pressure is applied to the product. The products in this datasheet are not insulators, they need to be handled as conductors. Care must be taken when in use, so that conductive material does not contact the surface or the edge of the Flex Suppressor(R) sheet. Insulation process should be performed when contact to conductive material is probable. Depending on the processing procedure, powdery substance may drop out from sheet surface or the edge, if the cutting of the sheet is performed. Depending on the location, care must be taken, as this powder may effect the component's performance. Any dust, oil or moisture must be cleaned from the surface of the installation area when using an adhesive tape to attach the sheet.The adhesive tape may begin to lose some of its adhesiveness after being in storage for six months. This has no impact on the EMI filtering effectiveness. Export Control For customers in Japan For products that are controlled items subject to the "Foreign Exchange and Foreign Trade Law" of Japan, the export license specified by the law is required for export. For customers outside Japan Flex Suppressor(R) products should not be used or sold for the use in the development, production, stockpiling or utilization of any conventional weapons, mass-destruction weapons (nuclear, chemical and biological weapons or missiles) or any other weapons.
