  • Publication number: 20200035404
    Abstract: A coil component includes a body and a coil portion disposed in the body and including first and second lead-out portions. Recesses are disposed along edges of one surface of the body, and expose the first and second lead-out portions to internal walls and lower surfaces of the recesses. First and second external electrodes are disposed in the recesses, and are connected to the first and second lead-out portions. A third external electrode is disposed in the recesses, and is connected to a connection electrode disposed on side surfaces of the body and on another surface of the body opposite to the one surface. An external insulating layer covers the connection electrode, and has an opening exposing at least a portion of the connection electrode. A shielding layers is disposed on the external insulating layer and in the opening and connects to the connection electrode.

  • Publication number: 20130063870
    Abstract: There is provided a tantalum capacitor, including: a chip sintered body formed by sintering a tantalum powder; and an anode lead-out line formed of niobium (Nb) and having an insertion region positioned inside the chip sintered body and a non-insertion region positioned outside of the chip sintered body, and thus, a niobium (Nb) wire is used as the anode lead-out line, thereby enhancing the binding force of the anode lead-out line with the tantalum powder, so that equivalent series resistance (ESR) and leakage current (LC) characteristics may be improved.

  • Publication number: 20120084954
    Abstract: There is provided a method of manufacturing a solid electrolytic capacitor including: forming a conductive polymer layer on a surface of a metal pellet; and forming a dielectric layer between the metal pellet and the conductive polymer layer. Because the conductive polymer layer is directly formed on the surface of the metal pellet, the conductive polymer layer can be uniformly formed, and because there is no need to form an electrode on the surface of the dielectric layer, the process can be reduced. In addition, because the uniform polymer film is formed irrespective of the size of metal pores and the shape of the capacitor, a capacity of the capacitor can be maximized.
