ドコイル。 A common mode coil that uses two flat U-shaped ferrite cores to create a closed magnetic circuit, wherein a plurality of band-shaped conductors are provided on the inner and outer surfaces of the core piece, and a connecting device that connects the inner and outer band-shaped conductors. A common mode coil characterized in that the two ferrite cores are fitted together to form a coil having a required number of turns, and assembled so that the magnetic fluxes of the two ferrite cores cancel each other out.
