Abstract
A noise filter includes a magnetic core including a magnetic material; and a distance adjusting member that accepts adjustment of a distance between a loop portion and the magnetic core, the loop portion being a portion of one or more conductor wiring lines wired in loop shape out of a first conductor wiring line and a second conductor wiring line.
Claims6
A noise filter comprising:
- a ground line connected between a first circuit mounted on a first conductor layer of a board and a second circuit mounted on the first conductor layer;
- a capacitor having a first end connected to the ground line;
- a first conductor wiring line connected between a second end of the capacitor and the second circuit and wired in a loop shape on the first conductor layer;
- a second conductor wiring line connected between the first circuit and the second end of the capacitor and wired in a loop shape on a second conductor layer of the board, the second conductor wiring line being coupled to the first conductor wiring line by a magnetic field;
- a magnetic core including a magnetic material;
- and
- a distance adjusting member to accept adjustment of a distance between at least one loop portion of loop portions and the magnetic core, the loop portions being wiring portions of the respective first and second conductor wiring lines,
- wherein the distance adjusting member accepts movement of the magnetic core in a horizontal direction of the first conductor layer or a horizontal direction of the second conductor layer.
