FSF Series (for NFC, Wireless Charger, RFID)

FSF Series (for NFC, Wireless Charger, RFID)

FSF Series is a thin flexible sintered ferrite sheet, which suppresses the effect of metals to improve communication of several applications, for example NFC, RFID device and wireless charger due to high magnetic permeability. ■ High Magnetic Permeability Improve properties of devices, for example increase distance of communication for several applications. FSF131 and FSF151 have relatively high μ' (about 130 - 150) and low μ'' at 13.56MHz, which improves performance of NFC and RFID devices. FSF201 and FSF501 have relatively high μ' (about 200 - 500) and low μ'' at 100-200kHz, which improves performance of wireless charger. ■ Thin flexible ferrite sheets Our thin ferrite sheet is laminated with sintered ferrite ceramics, PET film and adhesive tape. A slit formation enables the laminated ferrite sheets to be flexible. Yet, it still retains relatively high μ’ and low μ” at a tuned range of frequency, thus it is suitable for compact mobile devices.
