Abstract

A monolithic capacitor includes a plurality of monolithic ceramic capacitor elements provided with external electrodes at both ends thereof, solder layers arranged on the entire surfaces of the external electrodes of the monolithic ceramic capacitor elements, and metal terminals electrically connected to the external electrodes of the monolithic ceramic capacitor elements. The monolithic ceramic capacitor elements are joined to each other by the solder layers and are stacked on each other. The external electrodes of the monolithic ceramic capacitor elements are electrically connected to each other by the solder layers.

Description

[0001] 1. Field of the Invention

[0002] The present invention relates to a monolithic capacitor, and more particularly, the present invention relates to a monolithic capacitor having high capacitance and which includes a plurality of monolithic ceramic capacitor elements and metal terminals, and used, for example, as a substitute for a tantalum electrolytic capacitor for smoothing a power circuit in a DC-DC converter, or other suitable uses.

[0003] 2. Description of the Related Art

[0004] A monolithic capacitor provided with metal terminals is used in order to improve thermal shock resistance by ensuring bending strength and by relieving thermal stress. In such a monolithic capacitor, monolithic ceramic capacitor elements are supported by metal terminals so as not to contact a substrate. Furthermore, as disclosed in Japanese Unexamined Utility Model Publication No. 1-112032, metal terminals are bent. By using the techniques described above, it is also possible to decrease the differenc...
