Abstract
Abstract Adjustable multilayer monolithic capacitors having at least one connecting electrode embedded within or on a surface of the monolithic body and connected to one of the terminal ends, the connecting electrode having at least one additional conductive tab extending to the surface of the capacitor at a side or sides thereof distinct from the terminal ends. Incremental adjusting electrodes which are not in contact with the two terminal ends are included within the capacitor. Each of the adjusting electrodes also has an external conductive tab extending to the same side or sides of the capacitor as does the tab or tabs of the connecting electrode. Incremental adjustment of the capacitance of the capacitor is made by external interconnections, or conductive islands between the exposed tabs of the adjusting electrodes and the connecting electrodes.
