ABSTRACT:
An internally fused variable value ceramic capacitor is disclosed. The fuse component is formed by a reduced cross section area of electroding material formed as a portion of a pattern on a ceramic layer of the capacitor. The capacitor incorporates three terminals, namely a common terminal, a terminal connecting the electrode layers intervening between the electrodes connected to the common terminal, and a third terminal coupled by the reduced cross section fuse area to the second mentioned terminal. The intermediate electrodes may be divided into discrete areas, and less than all of the intermediate electrodes may be interconnected to thereby permit variation in the capacitance of the device. Further described is a circuit whereby the capacitor is connected to the power supply terminals of an integrated circuit device or the like.
