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.
