摘要： Disclosed herein is a common mode filter that includes a winding core part and first and second wires wound in a same direction around the winding core part. The first and second wires constitute a first winding block on one endmost side in an axial direction of the winding core part, a second winding block on other endmost side in the axial direction of the winding core part, and a third winding block positioned between the first and second winding blocks. The second winding block is a winding block at an odd-numbered position counted from the first winding block. The first and second wires cross each other in an area between the first and third winding blocks and in an area between the second and third winding blocks.

摘要： Disclosed herein is a coil component that includes first and second substrates, a first coil pattern formed on one surface of the first substrate, a second coil pattern formed on one surface of the second substrate, a first terminal electrode connected to one end of the first coil pattern and protruding from the first substrate, and a second terminal electrode connected to one end of the second coil pattern and protruding from the second substrate. The first and second substrates are laminated such that the first and second terminal electrodes overlap each other and are connected to each other.

摘要： A coil device includes a core, an inner coil portion, an outer coil portion, and an intermediate resin layer. The core includes a winding portion and a flange positioned at an end of the winding portion in an axial direction. The inner coil portion is constituted by winding a first wire around the winding portion. The outer coil portion is constituted by winding a second wire outside the inner coil portion. The intermediate resin layer exists between the inner coil portion and the outer coil portion.

摘要： 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.

摘要： 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.

摘要： Disclosed herein is a common mode filter that comprises a drum core including a winding core portion and a pair of flange portions provided at both ends of the winding core portion, and first and second wires wound around the winding core portion so as to form a pair-wire for each turn. The first and second wires includes one or a plurality of sparsely-wound portions in which the first and second wires are wound with adjacent pair-wires spaced from each other, and one or a plurality of closely-wound portions in which the first and second wires are wound with adjacent pair-wires in close contact with each other.
