Abstract
A common mode choke coil adapted for surface mount applications minimized in overall size (particularly in height), with an improved bonding coefficient. This common mode choke coil has a structure comprising a ferrite core consisting of a winding core and two square planar flanges with recesses formed therein, the square planar flanges being formed integrally on each end of a winding core thereof, a pair of external electrodes disposed on the square planar flanges, a plurality of windings wound about the winding core of the ferrite core and connected by thermal bonding to the external electrodes at the recesses provided in the left and right sides of each flange, and a ferrite plate adhesively bonded to the outermost surface of the windings to join the two flanges at both ends of the ferrite core, without an adhesive bonding to the flanges themselves. As a result, a closed magnetic circuit structure of a cubic component having a high rate of bonding coefficient is obtained.
