Abstract
Described is an improved common faced terminated multi-layer ceramic capacitor structure capable of embodying multiple capacitors of various maximum voltage and capacitance rating and method for its making. The structure features a ceramic body including multiple sections having a dielectric element and companion plate of one or more types, the types defined by the number and placement on the plate of plate tabs. The sections are aligned in the body such that the plates are located at displaced intervals in the direction of the body length while the plate tabs are located at displaced intervals in the direction of the body width and exposed at a common body face. Buses interconnect the tabs and plate in groups at common face. By selectively connecting the buses, one or more capacitors may be formed in the body. A structure is improved by providing grooves in the common face to align tabs in groups and to maintain the groups separated with the effect that the maximum voltage the structure can withstand is not reduced to mis-alignment of tabs during formation of the body. The method features steps for grooving the common face and simultaneously aligning tabs in the body.
