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) RFID
communication. While
61 and 67 material will
serve best at higher
frequencies (13.56 MHz).
FLEXIBLE FERRITE SHEETS
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.
PET FILM
FERRITE PLATE
ADHESIVE TAPE
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 displays 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
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.
APPLICATIONS
• Improved performance of RFID/NFC Antennas
in mobile devices, such as smart phones,
notebooks and tablet PC’s.
• Suppression of radiated noise on PCB’s and IC’s
from both internally and externally generated
sources out to the GHz band.
• Improved performance of Wireless Charging
Antenna Systems in both the stationary
charging station and mobile devices.
• Effective shielding of antennas and RF circuits
from the reflection and eddy currents induced
by metal surfaces.
