Common mode inductor

The utility model discloses a common-mode inductor, relates to the field of inductors, and can enhance the welding effect and prevent pseudo soldering and false soldering. Wherein the common-mode inductor comprises a first magnetic core; the terminal electrodes are arranged at the end part of the first magnetic core of the first magnetic core; a welding groove or a concave welding plane is arranged on one surface, far away from the end part of the first magnetic core, of the terminal electrode; and the coil is wound on the surface of the first magnetic core main body of the first magnetic core, and the leading-out end of the coil is welded with the terminal electrode. The leading-out end is placed in the welding groove or on the concave welding plane, so that the soldering tin is in full contact with the leading-out end, and the welding effect is enhanced. 本实用新型公开了一种共模电感，涉及电感器领域，能够增强焊接效果，防止虚焊和假焊。所述共模电感包括第一磁芯；若干端子电极，所述端子电极设置在所述第一磁芯的第一磁芯端部上；所述端子电极远离所述第一磁芯端部的一面设置有焊接槽或下凹焊接平面；线圈，所述线圈缠绕于所述第一磁芯的第一磁芯主体的表面，所述线圈的引出端与所述
