One world. One KEMET
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

Handling Precautions
Avoid high-temperature, humidity and direct sunlight. Storage environment should be below 40°C and below 70% relative
humidity.
The surface resistance value listed in this catalog is a reference value of the circuit parameter to indicate noise
suppression. The value does not mean the product’s insulation characteristics. The value may become lower if an excess
pressure is applied to the product.
Products in this catalog are not insulators. Please handle them as conductors. When in actual use, please be careful so that
conductive material does not contact the surface or the edge of the Flex Suppressor® sheet. Insulation process should be
performed when contact to conductive material is probable.
Depending upon the processing procedure, powdery substance may drop out from sheet surface or edge if cutting of the
sheet is performed by the customer. Please be careful as this powder may effect the component’s performance depending
on the location.
Clean away any dust, oil or moisture from the surface of the installing area when attaching the sheet using adhesive tape.
