RoHS compliant sheets are offered in six
material grades and four standard ferrite plate
thicknesses. The sheets are manufactured with
0.01 mm thick PET film on one side of the
ferrite material and 0.02 mm thick adhesive
tape on the opposite side.
The plate is "scored" in a rectangular grid
(2 mm x 2 mm); the PET film allows bending
without impacting effectiveness. Materials are
all NiZn, which display high volume resistivity.
This, along with the PET film, provides high
surface resistivity.
These ferrite sheets function primarily as
suppressors, blocking EM noise at lower
frequencies and absorbing at higher frequencies.
The degree of absorption will be proportional
to the resistive component of the material
permeability (µ’’) in higher frequency bands.
Material choice depends upon the frequency
of the signal to be suppressed.

RIGID FERRITE PLATES
Rigid and flexible ferrite plates can improve performance of RFID and
NFC antennas, as well as noise suppression on PCB's and IC's from
internal and external sources. Additionally, performance improvement
can be seen in reception and transmission on wireless charging
applications. The use of ferrite plates can prevent batteries from
overheating, and unintended current circulation in parts outside of
the charging circuit.
NFC applications benefit most from the use of our rigid 61 material
plates, and our M4 flexible plates. Wireless charging will see
performance improvements through the use of our 78/79
material in the form of rigid
plates. Fair-Rite's 78 material
will yield the best results for
low frequency (120-150 kHz)
applications. While 61 and
67 material will serve best at
higher frequencies (13.56 MHz).
APPLICATIONS
• NFC (Near Field Communication)
• RFID (Radio Frequency
Identification)
• Wireless Charging
• Shielding
