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.

Common mode filter

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 iturn located on the first section, a jturn located on the second section, and a kturn located on the third section. The iturn of the first wire is closer to the first end than the iturn of the second wire, the jturn of the first wire is closer to the second end than the jturn of the second wire, and the kturn of the first wire is closer to the first end than the kturn of the second wire.

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.

A device includes a core having a first end and a second end, and first and second wires wound around the core, each of the first and second wires having 1to Nturns counting from the first end to the second end, the 1to Nturns including an i&#x2212;1turn, an iturn, a jturn, and a j+1turn, where j is greater than i. The iturn of the first wire is closer to the first end than the iturn of the second wire, the i&#x2212;1turn of the second wire is closer to the first end than the iturn of the first wire, and the i&#x2212;1turn of the first wire is closer to the first end than the i&#x2212;1turn of the second wire.

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.

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. A predetermined one turn of the first wire crosses a predetermined one turn of the second wire a plurality of times.

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 iturn of the first and second wires counting from the cross point toward the first end, and a winding structure of an iturn of the first and second wires counting from the cross point toward the second end, are substantially symmetrical about the cross point.

A common mode filter includes a core, and first and second wires wound around the core. Each of the first and second wires includes at least i&#x2212;1turn, iturn, and i+1turn. The iturn of the first wire intersects with the iturn of the second wire without intersecting each of the i&#x2212;1and i+1turns of the second wire.
