摘要： An electromagnetic noise absorber has a pair of ferrite cores arranged with open ends of the ferrite cores facing each other. Each of the ferrite cores includes an axial portion, an outer cylindrical portion and a bottom portion and is constructed by coupling an end of the axial portion and an end of the outer cylindrical portion to the bottom portion. A slot is formed in the outer cylindrical portion and the bottom portion of each ferrite core such that the slot extends from the open end of the outer cylindrical portion to the bottom portion. The electromagnetic noise absorber can be easily attached to a signal line by placing the signal line in the slots and turning one of the ferrite cores. Since the signal line are wound around the axial portion of the ferrite cores, the signal line has a high impedance.

摘要： Three thin-film coils having insulating layers therebetween are laminated on the coil winding portion of the core member. A terminal electrode is electrically connected to the end portion of the third thin-film coil. A terminal electrode is electrically connected to the end portion of the first thin-film coil through the lead-out opening portions and separated areas. In this way, the thin-film coils are electrically connected in series between the terminal electrodes. Then, in the thin-film coils, the winding directions of the neighboring coils having an insulating layer therebetween are opposite to each other.

摘要： An LC component includes a coil conductor spirally wound around the outer peripheral surface of a wound core member having a substantially rectangular cross-section. A dielectric layer is arranged so as to cover the coil conductor. A capacitor electrode is provided on the dielectric layer so as to wind approximately once around the wound core member in the peripheral direction of the wound core member. The capacitor electrode includes first, second, third, and fourth surfaces. The capacitor electrode is divided by two cut grooves. One cut groove crosses the capacitor electrode obliquely from one side of the first surface of the capacitor electrode to the other side of the second surface adjacent to the first surface. Similarly, the other cut groove crosses the capacitor electrode obliquely from one side of the third surface of the capacitor electrode to the other side of the fourth surface adjacent to the third surface.

摘要： A method for easily sintering a magnetic core while preventing damage to the magnetic core caused by deformation or other problems, includes preparing a flattened tubular compact by forming the compact to have a flattened tubular shape and a through hole. A supporting plate made from a baked porcelain material or a metal material having a dimension that allows for insertion into the through hole of the flattened tubular compact, as well as a length that is sufficiently longer than that of the flattened tubular compact, is inserted through the through hole. The flattened tubular compact is placed inside of a sintering container having highly pure alumina powder spread therein so that the axial direction of the compact is horizontal. The flattened tubular compact is then sintered in a sintering furnace to produce the magnetic core.
