FLEX SUPPRESSOR® Magnetic Sheets for RFID

KEMET FLEX SUPPRESSOR® Magnetic Sheets for Radio Frequency Identification (RFID) prevent interference between a loop antenna and metallic objects and effectively improve the communication range of RFID. These flexible sheets utilize a polymer base blended with micron-sized magnetic powders dispersed throughout the material. KEMET FLEX SUPPRESSOR Magnetic Sheets for RFID improve magnetic flux convergence and increase the relative permeability (u') while keeping the magnetic loss (u'') low.
