摘要： A coil assembly for reducing variations in characteristic impedance includes a winding section having a first surface and a second surface on the opposite side of the winding section from the first surface, a plurality of first protrusions provided on the first surface, and a plurality of second protrusions provided on the second surface. These protrusions are identical in shape to each other and are arrayed linearly on their respective surfaces so that the first protrusions are offset from the second protrusions. Two conducting wires are wound between neighboring protrusions such that one wire contacts one of the neighboring protrusions, while the other wire contacts the other neighboring protrusion.

摘要： A common-mode filter with a drum type core including a core portion and flange portions. Electrodes are provided on the flange portions and a pair of wires are wound on the core portion. The wound pair of wires have ends connected to respective ones of the electrodes. Each of the flange portions has a groove between corresponding two of the electrodes and a separation protrusion for separating the groove into two lead-out groove portions. The pair of wires are wound on the core portion in such a distributed winding manner that an inter-wire distance between the pair of wires and a winding pitch between adjacent turns in each of the pair of wires are provided. The wires are one-by-one led out through the lead-out groove portions while separated by the separation protrusions so that the ends of the pair of wires are connected to respective electrodes.

摘要： A noise filter providing a simplified construction and capable of being used regardless of a diameter of a cable or a numbers of cables. The noise filter includes a core-holding section for holding a core, first and second cable-guiding sections, and two coupling sections coupling the first and second cable-guiding sections to ends of the core-holding section. The first and second cable-guiding section have truncated conical shape, and each divided into the four parts by a first to fourth slits arrayed in cruciform shape whose crossing position is coincident with an imaginary apex of the cable-guiding section. The coupling section has first to fourth circumferential elongated slots in communication with the proximal ends of the first to fourth slits.
