Flex Suppressor® EF Series Overview Applications The EF Series Flex Suppressor ® is an effective suppressor for high frequency noise generated from electronic devices. The flexible 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. • Radiation noise suppression for electronic equipment • Quasi-microwave range interference prevention inside and in between electronics • Mobile communications equipment, wireless equipment (Wi-Fi, Bluetooth), office automation equipment (personal computers, TFT LCD’s etc.), communication terminals in audio/video equipment, digital exchanges, etc. • ESD (electro static discharge) countermeasure Benefits • • • • • • Usable in quasi-microwave ranges Can be used in high-speed clocks (Up to 10 GHz) Thin, flexible 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 Part Number System EFR Series Type EFR EFX EFF EFA EFH EFG (01)- 240x240 T08 00 Thickness Standard Dimensions (mm) Tape 1 Type Adhesive Tape Thickness Tape 2 Type (003)- = 0.03 mm (005)- = 0.05 mm (007)- =0.07 mm (01)- = 0.1 mm (02)- = 0.2 mm (03)- = 0.3 mm (05)- = 0.5 mm (10)- = 1.0 mm 240 x 240 T08 = 0.03 mm T15 = 0.14 mm T22 = 0.05 mm T29 = 0.01 mm Blank = No adhesive tape © KEMET Electronics Corporation • P.O.

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. Reflected waves Reflected waves Incoming waves Metal surface High-frequency electric current Shielding material + radio wave absorber radio wave absorber Shielding material + Radio wave absorber transmitted waves and reflected waves can be minimized by mounting metal plates on the back of radio wave absorbers.

Storage environment should be below 40ºC 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. Information on environmentally influential substances The Flex Suppressor ® does not contain substances listed below: (1) Ozone depleting substance CFC (chlorofluorocarbon) Halon Carbon tetrachloride 1,1,1-Trichloroethane HCFC (hydrochlorofluorocarbon) HBFC (hydrobromfluorcarbon) Methyl bromide (2) Substances regulated by RoHS order Lead and lead compound Mercury and mercury compound Cadmium and cadmium compound (content of plastics are below 5ppm) Hexavalent chromium and hexavalent chromium compound PBB (polybrominated biphenyl) and its kind PBDE (polybrominated diphenylether) (3) Other environmentally influential substances (examples) PCB (polychlorinated biphenyl) Polychlorinated naphthalene Hexachlorobenzene Organotin compounds (tributyl tin, triphenyl tin) Asbestos Azo compound Chlorinated paraffin and its kind (paraffin chloride, Chlorinated paraffin and chloroparaffin) Radioactive substance PVC © KEMET Electronics Corporation • P.O.
