Noise Suppression Sheets/Magnetic Sheets/
Radio Wave Absorbers Flexield
FOR NOISE SUPPRESSION IFL MATERIALS
TDK’s Flexield is a highly flexible and shock resistant soft magnetic
sheet material consisting of magnetic material and resin.
It suppresses noise radiated from electronic devices across a wide
frequency range. Offering excellent flexibility in fabrication,
Flexield is a sheet-type noise reduction solution particularly suited
for high-frequency range.
FEATURES
They are flexible(not crack).
They are suited for thin and compact devices.
Available in a wide range of dimensions and shapes.
Conforming to RoHS Directive.
APPLICATIONS
Noise reduction for flexible cables used in mobile devices
(including notebook PC's, digital cameras, game machines, and
cellular phones).
Reduction of noise radiated from a wide variety of electronic
devices (including noise from CPU).
Reduction of specific absorbed radiation (SAR) from cellular
phones.
Reduction of internal EMI (resonance, crosstalk) inside a
shielded casing.
