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.

Coil component

Disclosed herein is a coil component that includes a substrate having a first surface, and first and second coil patterns coaxially formed on the first surface of the substrate and electrically isolated from each other. The first coil pattern has a plurality of turns including a first turn and a second turn. A predetermined turn of the second coil pattern is disposed between the first and second turns of the first coil pattern.

Coil component and wireless communication device having the same

Disclosed herein is an apparatus that includes a substrate having first and second surfaces opposite to each other, a first coil pattern formed on the first surface of the substrate, and a second coil pattern formed on the second surface of the substrate. The first coil pattern includes first and second lines, and the second coil pattern includes third and fourth lines. The first line is greater in a number of turn than the second line, and the third line is greater in a number of turn than the fourth line. The first line is connected to the fourth line, and the third line is connected to the second line.

A magnet temperature information output device is disposed on a rotating electrical machine including a stator and a rotor with a permanent magnet, and is arranged to output temperature information regarding a temperature of the permanent magnet. The magnet temperature information output device includes an element arranged to detect a magnetic flux and output an electrical signal responding to the detected magnetic flux as the temperature information. The element is disposed on the stator.

Magnet temperature information output device and rotating electrical machine

Disclosed herein is a coil component that includes a first coil pattern wound in a planar spiral shape. At least one turn constituting the first coil pattern is divided into a plurality of lines by a spiral slit, and a space width between the plurality of lines differs depending on a planar position.

Disclosed herein is a noise suppression sheet that includes a magnetic sheet and a first metal layer provided on one surface of the magnetic sheet. The first metal layer has a plurality of annular slits. The first metal layer is divided into a plurality of first areas surrounded respectively by the plurality of slits and a second area surrounding an entire periphery of each of the plurality of slits.

Noise suppression sheet

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 coil component that includes a first coil part spirally wound in a plurality of turns, the first coil part including a first turn positioned at an innermost periphery and a second turn positioned on an outer peripheral side relative to the first turn; and a second coil part spirally wound in a plurality of turns, the second coil part including a third turn positioned at an innermost periphery and a fourth turn positioned on an outer peripheral side relative to the third turn. The first turn and the fourth turn are connected to each other, and the second turn and the third turn are connected to each other.

Disclosed herein is a coil component that includes an insulating substrate, a first coil part formed on the first surface of the insulating substrate, and a second coil part formed on the second surface of the insulating substrate. At least an innermost turn of the first coil part is radially separated by spiral-shaped slits into three or more conductor parts. At least an innermost turn of the second coil part is radially separated by spiral-shaped slits into three or more conductor parts. Inner peripheral ends of respective innermost to outermost conductor parts of the three or more conductor parts of the first coil part are connected to inner peripheral ends of the respective outermost to innermost conductor parts of the three or more conductor parts of the second coil part.
