Abstract:
1. A multilayer ceramic electronic component comprising: a ceramic element assembly including a plurality of layered ceramic layers, the ceramic element assembly including opposed first and second principal surfaces and opposed first and second end surfaces, a direction of layering thereof being a direction that extends from the first principal surface to the second principal surface; a first external terminal electrode including a first terminal electrode main section provided on the first end surface and a first extended section continuous with the first terminal electrode main section and extending to the first and second principal surfaces; a second external terminal electrode including a second terminal electrode main section provided on the second end surface and a second extended section continuous with the second terminal electrode main section and extending to the first principal surface and the second principal surface; a first internal electrode disposed within the ceramic element assembly and extending to the first end surface so as to be electrically coupled to the first external terminal electrode; a second internal electrode disposed within the ceramic element assembly, being substantially coplanar with the first internal electrode, and extending to the second end surface so as to be electrically coupled to the second external terminal electrode; and a floating internal electrode disposed within the ceramic element assembly so as not to extend to either the first end surface or the second end surface, and opposed to the first internal electrode and the second internal electrode with one of the ceramic layers disposed therebetween; wherein a portion in which the first internal electrode and the floating internal electrode are opposed to each other defines a first effective region, and a second effective region is defined in a portion in which the second internal electrode and the floating internal electrode are opposed to each other; the multilayer ceramic electronic component further comprising: a relationship X1<Y1<(L−E) is satisfied where L is a dimension of the ceramic element assembly in a longitudinal direction that extends from the first end surface to the second end surface, X1 is a length dimension of the first internal electrode along the longitudinal direction, Y1 is a distance between the first end surface and an end of the first inner conductor that is adjacent to the second end surface, and E is a distance from the second end surface to an end of the second extended section, and within the ceramic element assembly, the first inner conductor is not coplanar with any other inner conductors.
