A solid electrolyte capacitor in a block of electrically insulative resin is provided with two electrodes connected by respective connecting tangs to output leads (+, -) and to a fuze test lead; one connecting tang (6) is formed by a first section (6B) fixed to one of the electrodes and projecting out of the resin block to form the fuze test lead, and a second section (6A) projecting out of the resin block to form a conventional terminal; an elongate strip (10) forms the fuze in one piece with the sections (6A,6B) so as to provide the only electrical connection between the sections; the fuze is coated with a supporting mass of thermally insulative resin extending between the two sections and embedded in the resin block.

Solid electrolyte capacitor with integral stamped fuze

A solid electrolytic capacitor embedded in an electrically insulating resin block has a capacitor body fitted with two electrodes which are connected by two connecting lugs, those of the output terminals (+, -) and a fuze test. One of the connecting lugs is formed of a first section attached to one of electrodes of the capacitor body and leading outside the resin block to form the fuze test terminal, and of a second section electrically insulated with respect to first section and the capacitor body and leading outside the resin block to form a normal operating terminal. The fuze element alone establishes an electric link between the first and second sections while being surrounded by the supporting mass of thermally insulating resin reaching from one of the sections to the other, while itself being embedded in the resin.

Solid electrolyte capacitor with testable fuze

A solid electrolyte capacitor body is embedded in an electrically insulative block of resin. Output terminals each connected to a respective electrode of the capacitor body project from the block. One output terminal includes a first section fixed to one of the electrodes and a second section electrically insulated from the first section and the capacitor body. A fusible member alone establishes electrical connection between the first and second sections. The fusible member is embedded in a rigid thermally insulative resin which extends between the first and second sections to couple them together mechanically.

Solid electrolyte capacitor with integral fuse

A porous tantalum body is pressed with a cavity compacted locally, and a connection wire is joined to the tantalum body within the cavity.

Capacitor anode and method

A porous tantalum anode body is sintered onto a strip having an incurvate member which is embedded in the body and an elongated portion of the strip which serves as the anode connection.
