Abstract
A multilayer ceramic capacitor includes a multilayer structure wherein [t12×L1]/N≥10, when a distance between a first edge that is an outermost edge of internal electrodes that is not connected to a first or second external electrode and a second edge that is an innermost edge of the internal electrodes that is not connected to the first or second external electrode is L1, each thickness of dielectric layers is t1, and a stack number of dielectric layers is N, wherein [t12×W1]/N≥10, when a distance between a first edge that is positioned at outermost of the internal electrodes and a second edge that is positioned at innermost of the internal electrodes is W1, and wherein R is larger than W1, when a curvature radius of a corner of an edge of the internal electrodes is R.
Claims8
A multilayer ceramic capacitor comprising:
- a multilayer structure in which each of a plurality of dielectric layers and each of a plurality of internal electrode layers are alternately stacked, a main component of the plurality of dielectric layers being ceramic, the multilayer structure having a rectangular parallelepiped shape, the plurality of internal electrode layers being alternately exposed to a first edge face and a second edge face of the multilayer structure, the first edge face facing with the second edge face;
- and
- a pair of external electrodes that are respectively provided on the first edge face and the second edge face,
- wherein t12×L1/N is equal to or more than 10, when a distance between a first edge that is an outermost edge of edges of the plurality of internal electrodes that is not connected to the first external electrode or the second external electrode in a first direction along a facing direction of the pair of external electrodes and a second edge that is an innermost edge of edges of the plurality of internal electrodes that is not connected to the first external electrode or the second external electrode in the first direction is L1 (mm), each thickness of the plurality of dielectric layers is t1 (μm), and a stack number of the plurality of dielectric layers is N,
- wherein t12×W1/N is equal to or more than 10, when a distance between a first edge that is positioned at outermost of the plurality of internal electrodes in a second direction intersecting with the first direction in a plane direction of the plurality of internal electrodes and the plurality of dielectric layers and a second edge that is positioned at innermost of the plurality of internal electrodes in the second direction is W1 (mm), and
- wherein R is larger than W1, when a curvature radius of a corner of an edge of the plurality of internal electrodes that is not connected to the first external electrode or the second external electrode is R (mm).
