ABSTRACT:
A solid electrolytic capacitor comprises a capacitor element including a chip body and an anode wire projecting from the chip body, an anode lead electrically connected to the anode wire, a cathode lead paired with the anode lead, a first fuse wire connecting electrically between the chip body and the cathode lead, and a resin package enclosing the capacitor element, part of the anode lead, part of the cathode lead, and the first fuse wire. The capacitor further comprises an auxiliary lead separate from the anode and cathode leads, and a second fuse wire for electrically connecting the auxiliary lead to one of the chip body and the anode lead within the resin package. In an alternative embodiment, there is only a single fuse wire, the fuse wire acting both as a temperature fuse and as an overcurrent fuse.
