Built Into Tomorrow

Benets

• 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,exible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)

• Available in SHF band (EFS)

Overview

The KEMET Noise Suppression Sheet FLEX SUPPRESSOR

is effectively designed for high frequency noise that is

generatedfromtheelectronicdevices.Theexible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

FLEX SUPPRESSOR® Noise Suppression Sheet Shielding Shielding materials (metal, electrically conductive material) Shield While transmitted waves can be minimized, most of the incoming waves are reflected, causing internal interference. High frequency electric current occurs on the metal surfaces and the reflected noise occurs at the shielding joints, metal openings, and other parts when the grounding is poor.
