Magnetic Sheets for RFID Flexield 

## IFW series 

(2/8) 

## **Magnetic Sheets for RFID Flexield** 

**Product compatible with RoHS directive** 

## **Overview of IFW series** 

## **FEATURES** 

Solution item for protecting your cards against interference and skimming 

Hybrid construction consisting of both magnetic and metal layers 

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 

Available on a roll or in sheet form 

Protects system from metal objects located directly behind coils 

## **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 

High EMI level conditions where magnetic layer alone those not have sufficient attenuation 

PCB, FPC, ribbon cable data/address lines
