## IFL series 

(2/6) 

## **Magnetic Sheets for RFID Flexield** 

**Product compatible with RoHS directive** 

## **Overview of IFL Series** 

## **FEATURES** 

High permeability (µ') and low magnetic loss (µ") materials up to 13.56MHz 

Multiple materials and thickness available to optimize coil Quality (Q) factor 

High flexibility which allows sheets to easily be formed to desired shape 

Non conductive surface allows for metal coils to be directly applied to magnetic sheet 

Protects system from metal objects located directly behind coils 

Available on a roll or in sheet form 

## **APPLICATION** 

Improving antenna reception performance and sensitivity in RFID readers/writers 

Isolation of magnetic field in metal smart cards and tags 

- NFC transmitters and receivers 

Shielding for low power magnetic resonance wireless power transfer systems
