EMC common mode choke cores

EMC common mode choke cores
Reliable quality,bright surface,accurate size,uniform coating thickness

Iron core of the common mode inductors
Characteristics:
common mode chokes (CMC) are used to suppress EMI with a
wide spread application of electronic equipments and
electromagnetic interference (EMI) in electrical network.
And CMC are made of Fe-based Nanocrystalline, with high permeability; excellent
frequency dependence of impedance; large
adjustable range
for permeability; outstanding performance at unbalanced current
