TDK IFL & IFW Flexield Magnetic Sheets
TDK IFL and IFW Flexield Magnetic Sheets are highly flexible, allowing them to be easily formed to the desired shape. These thin sheets protect a system from any metal objects located directly behind coils, and their non-conductive surface allows for metal coils to be directly applied to the magnetic sheet. These RoHS-compliant sheets are available on a roll or in sheet form and have an operating temperature range of -40°C to +85°C. TDK IFL and IFW Flexield Magnetic Sheets are ideal for NFC transmitters and receiver applications and for improving antenna reception performance and sensitivity in RFID readers/writers. The sheets can also be used for the isolation of the magnetic field in metal smart cards and tags.
