Multilayer capacitor and method of fabricating the same

A plurality of internal electrodes (17, 18) are formed in a laminated state with a respective dielectric layer (12b, 12c) held between each pair of adjacent internal electrodes to give capacitance. A pair of external electrodes (15, 16) are electrically connected to associated internal electrodes in order to connect the capacitance to external circuits. Each internal electrode comprises a capacitance forming portion (19, 22) a take-out (external connection) portion (20, 23) connected to the associated external electrode, and a fuse portion (21, 24) which electrically interconnects the capacitance forming portion and take-out portion. The fuse portion is melted earlier than the capacitance forming portion and take-out portion by the Joule heat produced when a current higher than a predetermined value flows through the fuse portion.

Laminated capacitor with fuse function

A laminated ceramic capacitor, comprising a plurality of internal electrodes (1) composed of a base metal to give electrostatic capacity and configured in a laminated state with non-reducing ceramics (2) mutually held between each of two of the internal electrodes, and a pair of external electrodes (3) connected to the associated ones of the internal electrodes (1) for taking out the electrostatic capacity. The external electrodes (3) are formed with copper which contains zinc borosilicate glass.
