  • 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.

  • Publication number: 20230066655
    Abstract: In the coil component, since the contact area between the external terminal electrode and the element body is increased by the protrusion of the external terminal electrode, the external terminal electrode and the element body are more closely attached to each other. Therefore, the attachment strength between the external terminal electrode and the element body can be improved. Hence, it is possible to suppress peeling of the external terminal electrode from the element body.

  • Patent number: 11569024
    Abstract: An upper end portion and a lower end portion of a second magnetic portion of a coil component are further away from a coil than when a third part and a fifth part are not present. For this reason, a magnetic flux is unlikely to be concentrated in the upper end portion and the lower end portion of the second magnetic portion, so that magnetic saturation is unlikely to occur. Therefore, improvement of direct current superimposition characteristics is realized in the coil component.

  • Publication number: 20220415566
    Abstract: An electronic component preventing peeling of an external terminal is provided. Since each of the external terminal electrodes on the upper face has a U-shaped outline, stress concentration is less likely to occur at an inner end portion than in the external terminal electrode having a corner at the inner end portion. Therefore, for example, even when an impact is applied, a situation in which the external terminal electrode peels off from the upper face due to stress concentration is prevented.

  • Publication number: 20210151248
    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.
