EF series shielding sheets can be used for resonance and wave suppression and are effective for suppressing high frequency noise from electronic devices. These flex suppressor sheets from KEMET are constructed from a polymer base with dispersed micron sized magnetic powders. Due to the thin, flexible properties of these sheets, there are virtually no restraints on where you can use them.

EFR type flex suppressor sheets come in range of thicknesses and offer high permeability of μ60. These shielding sheets are flame retardant and have a UL 94 V-0 certification

Can be cut to any size or shape
Thin and flexible material
Suitable for use in portable equipment
Small installation time required
Resonance wave suppression
Electromagnetic wave suppression

Suitable applications for these flex suppressor shielding sheets include mobile communication equipment, office automation, digital exchanges and communication terminals in audio/video equipment. You can also use these EF shielding sheets for quasi-microwave interference in between and inside electronic devices. Flex suppressor sheets are recommended as an ESD (electro static discharge) countermeasure and also for use in electronic equipment to suppress radiation noise.
