Benets

• Usable in quasi-microwave ranges

• Can be used in high-speed clocks (Up to 10 GHz)

• Thin,exiblematerialusedinportableequipment

• Virtually no limitation in where it can be used

• Less time required for installation

• Resonance suppression – controls the high frequency

current and suppresses unwanted electromagnetic

resonance by creating impedance

• Electromagnetic wave suppression – suppresses the

electromagnetic wave intruding the sheet by the magnetic

loss of its composition

Overview

The EF Series Flex Suppressor

is an effective suppressor

for high frequency noise generated from electronic devices.

Theexiblesheetisapolymerbaseblendedwithmicron

sized magnetic powders dispersed into the material. The EF

Series are effective for resonance and wave suppression,

and can be cut into virtually any shape.

Applications

• Radiation noise suppression for electronic equipment

• Quasi-microwave range interference prevention inside

and in between electronics

• Mobile communications equipment, wireless equipment

(Wi-Fi,Bluetooth),ofceautomationequipment(personal

computers, TFT LCD’s etc.), communication terminals in

audio/video equipment, digital exchanges, etc.

• ESD (electro static discharge) countermeasure

Flex Suppressor ® EF Series 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 reflected noise occurs at the shielding joints, metal openings, and other parts when the grounding is poor.
