Noise Suppression Sheets/Magnetic Sheets/Radio Wave Absorbers
Flexield®
FOR NOISE SUPPRESSION IRL, IRJ, IVM, IRB, IRE MATERIALS
Flexield® is an absorptive electromagnetic shielding material con-
sisting of magnetic material and resin. It suppresses noise radiated
from electronic equipment over a wide range of frequencies, offers
flexibility in fabrication and delivers particularly excellent perfor-
mance in high frequency ranges. Flexield® is the ideal sheet-type
noise reduction product for mobile devices including notebook
PCs, digital cameras and cell phones.
FEATURES
• They are flexible(Will not crack).
• They are suited for thin and compact devices.
• Available in a wide range of dimensions and shapes.
• The products in the line-up support a wide range of frequency
bands (50MHz to 30GHz).
• Excellent performance at high frequencies ( 300MHz).
• Environmentally products(All products: Lead-free) are also
available.
• Product Conforming to RoHS Directive
APPLICATIONS
• Electromagnetic noise reduction for electric equipment
(especially for mobile equipment)
Internal EMI, resonance reduction(mounting inside a shielded
box)
• RF-block
• Amplifier
Radiated noise reduction(Circuit, IC, flat cable)
Surface current suppression
• Improvement of noise immunity
• SAR reduction for mobile phone
• Electrostatic discharge countermeasure
• Improved antenna reception sensitivity.
