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.

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 pulse transformer includes a winding drum and a coil portion in which wires are wound around the winding core. The coil portion includes a first general winding area, a second general winding area, and a low density winding area. In the first general winding area, the wires are mutually closely wound around the winding core. In the second general winding area, the wires continuing from the wires of the first general winding area are mutually closely wound around the winding core. The low density winding area is formed along a winding axis of the winding core between the first general winding area and the second general winding area and has a low winding density of the wires along the winding axis.

摘要： Disclosed herein is a common mode filter that includes: a winding core part including first and second winding areas and a third winding area positioned between the first and second winding areas; 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 wound in the first winding area and a second winding block wound in the second winding area. The first and second wires cross each other in the third winding area. Each of the first and second winding blocks has first and second winding layers. The difference in a number of turns between the first winding layer and the second winding layer is larger in the first winding block than in the second winding block.
