Noise Suppression Sheets/Magnetic Sheets/Radio Wave Absorbers
Flexield
®
FOR RFID MAGNETIC SHEETS IRL, IRJ, IVM, IRB, IRE MATERIALS
Flexield
®
is a highly flexible and shock resistant soft magnetic
sheet material consisting of magnetic material and resin. It is
highly effective when used in reader/writers or attached to tags
and metal components used in emerging RFID systems based on
the 13.56MHz band. With an extensive lineup of products that
deliver excellent permeability, Flexield
®
allows designers to match
impedance with ease and delivers excellent magnetic conver-
gence. These products are also more lightweight and resistant to
shock compared to sintered ferrite materials.
FEATURES
• They are flexible(Will not crack).
• They are suited for thin and compact devices.
• Available in a wide range of dimensions and shapes.
• Environmentally products(All products: Lead-free) are also
available.
APPLICATIONS
• For improving reception performance in RFID reader/writers.
• Integrate IC cards with metal.
• Integrate IC tags with metal.
