Application classification and selection of common mode inductors
For the same common-mode series, packaging structures of different sizes are suitable for different current sizes and filtering bandwidths: the larger the size, the lower the magnetic resistance of the magnetic core, which can reduce the number of winding turns, so that the wire diameter of the copper wire can be enlarged and a larger current loop can be used; the higher the inductance value or the lower the stable frequency of the material's magnetic permeability, the narrower the applicable filtering bandwidth, and such a common-mode inductor placed in the loop is likely to have no noise suppression effect on the high-frequency end.
