Abstract
Abstract A monolithic capacitor component includes at least first and second layers separated by dielectric material and having nonoverlapping terminal portions of the electrode layers. Aligned with each electrode layer in the nonoverlapped area of the terminal portion is a nonactive electrode segment which is spaced from the electrode layer with which it is aligned. In the manufacture of such a component at least two electrode layers each having discrete electrode sections are separated dielectric and stacked and arranged relative to one another to provide overlapped terminal portions of the discrete electrode sections in the electrode layers whereby it is possible to sever the stacked and arranged dielectric and electrode layers in the area of the overlapped terminal portions to provide monolithic capacitor constructions.
