WebDec 13, 2015 · One way to picture things for selection of noise filter chokes is to consider the choke (or filter bead) impedance as part of a impedance divider. The other part of the impedance becomes either the source impedance of inputs or load impedance of outputs as referenced to the GND system. WebCommon mode chokes made of nanocrystalline soft magnetic material FINEMET®. With having high permeability and low Q factor, FINEMET® common mode chokes have high impedance over a wide frequency range. Our common mode chokes suppress common mode noise effectively, and contribute to downsizing EMC(EMI) compoents.
