EMI Core – ESD-SR Snap-on Cores for Round Cables for Low & High Frequency (with case) Magnetic Permeability of Ferrite Material In order to achieve most efficient noise reduction, it is important to select the material according to the target frequency band. Depending on its magnetic permeability, a particular ferrite material will be effective in a certain frequency band.
