STACKED COMMON MODE CHOKE COIL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a stacked common mode choke coil employing a bifilar solenoid winding having a high coupling factor. SOLUTION: The stacked common mode choke coil comprises a coil formation layer 20 where a first coil 21 and a second coil 22 are formed by bifilar winding on the circumferential surface of a magnetic body in the lateral winding direction orthogonal to the thickness t of the magnetic body, and insulator layers 12 formed on the upper and lower surfaces of the coil formation layer 20.
