Core material: mainly nanocrystalline; wire material: not discussed here;
Compared to UF, there is not much advantage in terms of voltage resistance: I came up with my own idea because I have seen many magnetic ring common mode circuits separated by cable ties,
Baidu explains the principle of common mode inductance more clearly than I do:
Common mode inductors are key components in switching power supplies used to suppress common mode noise.
In practical applications, the selection and evaluation of common mode inductors need to consider the following key parameters:
Operating Frequency Range: Common mode inductors need to operate effectively within the set operating frequency range.
