Abstract:
1. A monolithic ceramic capacitor comprising: a ceramic body including a plurality of stacked ceramic layers, first and second principal surfaces extending in a lengthwise direction and a widthwise direction perpendicular to the lengthwise direction, first and second lateral surfaces extending in a thickness direction perpendicular to both the lengthwise direction and the widthwise direction and in the lengthwise direction, and first and second end surfaces extending in the widthwise direction and the thickness direction; first and second inner electrodes alternately arranged inside the ceramic body so as to be opposed to each other in the thickness direction with respective ceramic layers of the plurality of ceramic layers interposed between adjacent ones of the first and second inner electrodes; and additional ceramic layers disposed on end surfaces of the stacked ceramic layers in the widthwise direction so as to cover the end surfaces of the stacked ceramic layers; wherein among the plurality of ceramic layers, a number N of the respective ceramic layers disposed between the first inner electrodes and the second inner electrodes is at least 232; the ceramic body further includes: the side gap portions are defined by the additional ceramic layers; a proportion of volume occupied by the first and second inner electrodes in the ceramic body is at least about 0.37; a size of each of the side gap portions in the widthwise direction is about 40 μm or less; and a length of the ceramic body in the lengthwise direction is 1.1 mm, a width of the ceramic body in the widthwise direction is 0.63 mm, and a thickness of the ceramic body in the thickness direction is 0.63 mm.
