Noise Suppression Sheet
Overview
The KEMET Noise Suppression Sheet Flex Suppressor®
is effectively designed for high frequency noise that is
generated from the electronic devices. The flexible sheet
is a polymer base, blended with micron-sized magnetic
powders dispersed throughout the material. These sheets
are effective for electromagnetic wave and resonance
suppression, and can be cut into a variety of shapes and
sizes.
Applications
• Radiation noise suppression for electronic equipment,
especially mobile phone, display, digital still camera,
digital video camera, notebook PC and tablet, car
infortainment
• Quasi-microwave range interference prevention inside
and in-between electronics, desense in FM radio, digital
TV, LTE, GPS, Wi-Fi, Bluetooth and optical transceiver
• Electro static discharge (ESD) countermeasure
• Enhanced wireless power transfer
Benefits
• Electromagnetic wave suppression – the electromagnetic
wave enters through the sheet and is suppressed by losing
its magnetic structure
• Resonance suppression – controls the high frequency
current and suppresses unwanted electromagnetic
resonance by creating impedance
• Wide range of frequencies available from MHz band to
GHz band
• Thin, flexible material used in portable equipment
• Virtually no limitation to where it can be used
• Less time required for installation
• Easily cut into any shape
• RoHS compliant and halogen-free
• AEC-Q200 (FF1 and EFF4)
