Claim 1
Independent Claim
183 words
A capacitive device comprising a plurality of slab-like, porous tantalum anode bodies having formed thereon a dielective oxide film and having an electrolyte layer of manganese dioxide, each of said anode bodies having tantalum riser wires extending therefrom and being arranged in a parallel row with side faces of the anode bodies adjacent to but spaced apart from each other and with the individual riser wires extending in the same direction, a first strip-like metallic terminal extending transversely of the row of anode riser wires and electrically connected to each of said anode riser wires to form an anode terminal for said capacitance device, a second strip-like terminal extending transversely of the row of slab-like bodies, a conductive counterelectrode coating covering the major portion of the electrolyte layer on the surface of each anode body and a body of solder covering at least portions of the conductive counterelectrode coatings on the individual slab-like bodies and bridging the spaces between said bodies and electrically connecting said conductive coatings in parallel to the second strip-like terminal to provide a cathode terminal for said capacitance device.
