    Abstract: A multi-layered ceramic capacitor (100), comprising:
    a body (110) including: dielectric layers (111) stacked in a first direction (Z) and a first internal electrode (121) and a second internal electrode (122) interposed between the dielectric layers (111);
    - a first surface (S1) and a second surface (S2) facing each other in the first direction (Z);
    - a third surface (S3) and a fourth surface (S4) facing each other in a second direction (Y) perpendicular to the first direction (Z); and
    - a fifth surface (S5) and a sixth surface (S6) facing each other in a third direction (X) perpendicular to the first direction (Z) and the second direction (Y);
    - a first external electrode (141) disposed on the third surface (S3) of the body (110) and electrically connected to the first internal electrode (121); and
    - a second external electrode (142) disposed on fourth surface (S4) of the body (110) and electrically connected to the second internal electrode (122), wherein
    - the body (110) includes a first inclined portion (151) in which at least one of edge regions of the first surface (S1) are chamfered and
    - a second inclined portion (152) in which at least one of edge regions of the second surface (S2) are chamfered,
    - a ratio of a first length (d1) of the first inclined portion (151) along the second direction (Y) to a second length (d2) of the second inclined portion (152) along the second direction (Y) is 0.67 to 1.5,
    - a ratio of a third length (d3) of the first inclined portion (151) along the first direction (Z) to a fourth length (d4) of the second inclined portion (151) along the first direction is 0.4 to 2.5,
    - a ratio of the third length (d3) to a fifth length (d5) from the first surface (S1) to the second surface (S2) along the first direction (Z) is 0.17 to 0.42, and
    - a ratio of the fourth length (d4) to the fifth length (d5) is 0.17 to 0.42.

    Abstract: A multilayer ceramic capacitor includes a body including a capacitance region in which a plurality of first internal electrodes and a plurality of second internal electrodes are alternately stacked in a first direction with a dielectric layer interposed therebetween, and first and second external electrodes disposed on the body and spaced apart from each other to be connected to the plurality of first internal electrodes and the plurality of second internal electrodes, respectively, wherein the capacitance region includes one or more groups of first openings. The first openings in each group overlap in the first direction and are continuously open in two or more internal electrodes of the plurality of first and second internal electrodes, and a number of internal electrodes included in each group is less than a total number of the plurality of first internal electrodes and the plurality of second internal electrodes.

    Abstract: A multilayered capacitor includes a capacitor body including dielectric layers, a pair of first internal electrode layers with a first one of the dielectric layers interposed therebetween and a pair of second internal electrode layers stacked with a second one of the dielectric layers interposed therebetween, and a first external electrode and a second external electrode on both sides of the capacitor body in a longitudinal direction of the capacitor body. The pair of first internal electrode layers are respectively connected to the first external electrode and the second external electrode and the pair of second internal electrode layers are respectively connected to the first external electrode and the second external electrode. In a width direction of the capacitor body, an average length of the pair of first internal electrode layers and an average length of the pair of second internal electrode layers are different.
