Abstract: A device includes a core having a first end and a second end, and first and second wires wound around the core, where the core has first, second, and third sections, the second section being arranged between the first and third sections. Each of the first and second wires includes an ith turn located on the first section, a jth turn located on the second section, and a kth turn located on the third section. The ith turn of the first wire is closer to the first end than the ith turn of the second wire, the jth turn of the first wire is closer to the second end than the jth turn of the second wire, and the kth turn of the first wire is closer to the first end than the kth turn of the second wire.

Abstract: Disclosed herein is a differential mode filter that includes first and second terminal electrodes provided on a first flange part of a core, and first and second wires wound around a winding core part of the core in an opposite direction to each other and connected respectively to the first and second terminal electrodes. The first and second wires cross each other on the winding core part to form a plurality of crossing portions that include first, second, and third crossing portions that are first, second, and third occurrences counting from the one end of the first and second wires, respectively. A first crossing angle between the first and second wires at the first crossing portion is larger than at least one of second and third crossing angles between the first and second wires at the second and third portions, respectively.

Abstract: A device is provided that includes a core having a first end and a second end, and first and second wires wound around the core so as to cross each other on the core to form a cross point. The a winding structure of an ith turn of the first and second wires counting from the cross point toward the first end, and a winding structure of an ith turn of the first and second wires counting from the cross point toward the second end, are substantially symmetrical about the cross point.

Abstract: In a coil component, a shortest distance from a longitudinal wall of a flange portion of a drum core to a wire fixing portion is smaller than a shortest distance of the longitudinal wall to an electrode wire connecting portion by a convex portion formed at the longitudinal wall of the flange portion. That is, since a gap between the flange portion of the drum core and the wire fixing portion is small (or there is no gap), the wire fixing portion can be sufficiently bent. Accordingly, the wire can be securely fixed by a wire fixing portion of a metal terminal.
Abstract translation: 在线圈部件中，从鼓芯的凸缘部分的纵向壁到线固定部分的最短距离小于通过形成在纵向壁处的凸部的纵向壁与电极线连接部分的最短距离 的凸缘部。 也就是说，由于鼓芯的凸缘部分和电线固定部分之间的间隙小（或没有间隙），所以电线固定部分可以被充分弯曲。 因此，金属丝可以通过金属端子的线固定部牢固地固定。

Abstract: A common mode filter includes first and second wires wound around a winding core portion by the same number of turns. Each of the first and second wires is wound by a number m1 of turns in a first winding area and wound by a number m2 of turns in a second winding area. A distance D1 between an n1th turn (1≦n1≦m1−1) of the second wire and an n1+1th turn of the first wire is shorter than a distance D2 between an n1th turn of the first wire and an n1+1th turn of the second wire in the winding area. A distance D3 between an n2th (m1+1≦n2≦m1+m2−1) turn of the first wire and an n2+1th turn of the second wire is shorter than a distance D4 between an n2th turn of the second wire and an n2+1th turn of the first wire in the winding area.
