  • Patent number: 12087497
    Abstract: In a coil component, a main body portion is made of a metal magnetic powder-containing resin, and thus a resin component appears on end surfaces of the main body portion. In addition, since external terminal electrodes are made of a conductive resin, a resin component also appears on the surfaces of the external terminal electrodes. Accordingly, insulating coating layers are integrally covered with high adhesion with the end surfaces of the main body portion and the external terminal electrodes by the insulating coating layers coming into contact with the end surfaces of the main body portion so as to straddle the external terminal electrodes.

  • Patent number: 12068099
    Abstract: In a coil component, a first planar coil and a second planar coil are wound around a common magnetic core and are magnetically coupled to each other. However, the first planar coil and the second planar coil are not electrically connected to each other and form coil structures which are separate from each other. Thus, as compared with a case in which the first planar coil and the second planar coil form one coil structure, the first planar coil and the second planar coil are less likely to affect each other's characteristics.

  • Patent number: 11894177
    Abstract: In an electronic component, a terminal electrode has a thickest portion and a part thinner than the thickest portion. Accordingly, an increase in solder fillet forming region occurs when the electronic component is solder-mounted onto a predetermined mounting substrate. In the electronic component, mounting strength is improved as a result of the increase in solder fillet forming region. In addition, in the electronic component, the thickest portion overlaps a bump electrode in a direction orthogonal to the lower surface of an element body. Accordingly, the impact that is applied to the electronic component during the mounting onto the mounting substrate is reduced and the impact resistance of the electronic component is improved.

  • Patent number: 11854733
    Abstract: In a coil component, a double coil is configured of a first coil portion and a second coil portion, and a first through conductor of the first coil portion and a second through conductor of the second coil portion are adjacent to each other. Thus, the first coil portion and the second coil portion have enhanced magnetic coupling at locations (that is, the first through conductor and the second through conductor) at which planar coil patterns of upper and lower surfaces of an insulating substrate are connected, in addition to magnetic coupling in the planar coil patterns wound around a through hole. Therefore, according to the coil component, a high coupling coefficient between the first coil portion and the second coil portion is realized.
