  • Publication number: 20240420892
    Abstract: A multilayer ceramic capacitor includes a first counter portion including first and second regions, and a first middle region located between the first and second regions and including coverage higher than coverages thereof, a second counter portion including third and fourth regions, and a second middle region located between the third and fourth regions and including coverage higher than coverage thereof. A thickness of each of the first and second middle regions is about 101.6% or more and about 111.3% or less of a thickness of each of the first, second, third, and fourth regions, and a difference between coverage of each of the first and second middle regions and coverage of each of the first, second, third, and fourth regions is about 2.2 percentage points or more.

  • Publication number: 20240420891
    Abstract: A multilayer ceramic capacitor includes first and second counter portions. The first counter portion includes a first middle region and first and second regions. The second counter portion includes a second middle region, third and fourth regions. The first middle region has coverage higher than coverage of the first and second regions. The second middle region has coverage higher than coverage of the third and fourth regions. A dimension of each of the first and second middle regions is shorter than a distance between first and second external electrodes. A dimension at a center of an exposed portion in the length direction is longer that a maximum distance in a lamination direction between first and second covered portions, and shorter than a maximum distance in the lamination direction between both sides of the first and second external electrodes.

  • Publication number: 20240420888
    Abstract: A multilayer ceramic capacitor includes first, second, third, and fourth regions each adjacent to a corresponding one of end surfaces, a first middle region between the first and second regions, located closer to an outside of a multilayer body, and having higher coverage, a second middle region between the third and fourth regions, located closer to the outside of the multilayer body, and having higher coverage, a first sloped portion coupling the first region and the first middle region, a second sloped portion coupling the second region and the first middle region, a third sloped portion coupling the third region and the second middle region, and a fourth sloped portion coupling the fourth region and the second middle region.

  • Publication number: 20240420894
    Abstract: A ceramic capacitor includes a multilayer body, and first and second external electrodes including first and second based electrode layers. The first and second external electrodes are spaced from each other and provided on end surfaces of the multilayer body in a length direction. The first and second base electrode layers each include a metal portion and non-metal portions in the metal portion. In a cross sectional view perpendicular or substantially perpendicular to a width direction, an average area of the non-metal portions in a first population of the non-metal portions, each having a circularity of about 0.4 or less, is about 10 ?m2 or more, and a proportion of the plurality of non-metal portions in each of the first and second base electrode layers is about 8.2% or more.

  • Publication number: 20230335336
    Abstract: A multilayer ceramic electronic component includes a multilayer body including ceramic layers and internal conductive layers and a pair of external electrodes on both ends of the multilayer body in a length direction. The internal conductive layers include first internal conductive layers and second internal conductive layers. The pair of external electrodes include a first external electrode including a first base electrode layer connected to the first internal conductive layer, and a second external electrode including a second base electrode layer connected to the second internal conductive layer. The first and second base electrode layers each include a metal portion and non-metal portions in the metal portion. In a cross-sectional view perpendicular or substantially perpendicular to a width direction, an average area of non-metal portions in a first population of non-metal portions each with a circularity about 0.4 or less is about 12 ?m2 or less.
