Abstract: A fused solid electrolytic capacitor comprises a six sided body having a pair of spaced parallel sides, one of which will be positioned next to any mounting structure which supports the capacitor. One end of a fuse wire may be connected to either of the spaced parallel sides. The other end of the fuse wire extends through an open passageway in an insulating block to a cathode electrode, thereby giving the fuse wire a fixed length. This way there is no danger that the fuse wire may short circuit along its length to either the capacitor body or the cathode electrode. A result is a smaller capacitor which may be manufactured with a greater harvest yield, as compared to the size and yield of similar prior art fused solid electrolytic capacitors.
