  • Patent number: 9165714
    Abstract: An electronic component, preferably in the form of a laminated ceramic capacitor, which suppresses the growth of whiskers and has excellent solderability, includes an electronic component element in the shape of, for example, a rectangular parallelepiped. External electrodes of terminal electrodes are located on first and second end surfaces of the electronic component element. First plated films including plated Ni are located on the surfaces of the external electrodes. Second plated films are located on the surfaces of the first plated films. The second plated films have stacked structures including first plated layers and second plated layers. The second plated layers have lower degrees of densification than the first plated layers.

  • Patent number: 8709612
    Abstract: A laminated ceramic capacitor includes a rectangular solid-shaped electronic component element. External electrodes of terminal electrodes are disposed at one end surface and the other end surface of the electronic component element. First plated films including a Ni plating are disposed on the surfaces of external electrodes. On the surfaces of the first plated films, second plated films containing Sn are disposed as Sn-plated films defining outermost layers of the external electrodes. The second plated films have a polycrystalline structure, and flake-shaped Sn—Ni alloy grains are located at a Sn crystal grain boundary and within a Sn crystal grain, respectively.
