Abstract:
Disclosed are a common-mode coil component and a manufacturing method therefor. The common-mode coil component comprises a coiling core part, a first outer electrode, a second outer electrode, a third outer electrode, and a fourth outer electrode, wherein the coiling core part comprises a wire coiling center part with a first flange part and a second flange part formed on one side and the other side respectively, the first outer electrode and the third outer electrode are arranged on the first flange part and the second flange part respectively, and the second outer electrode and the fourth outer electrode are arranged on the first flange part and the second flange part respectively; and a first wire and a second wire are wound around the coiling core part to form a first coiling area, a switching area, a second coiling area and a third coiling area, and are fixed on the outer electrodes to form a double-layer segmented structure. The common-mode coil component can be obtained through the manufacturing method. A mode translation characteristic of the common-mode coil component can be kept to a minimum by the present invention.
