PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor containing sinter-bonded anode leadwires.SOLUTION: Provided is a capacitor containing a solid electrolytic capacitor element having a porous anode body and an anode lead assembly. At least one wire of the lead assembly is electrically connected to the anode body for connection to an anode termination. The lead assembly contains first and second lead wires embedded within the anode body and extending therefrom in a longitudinal direction. The first and second wires are bonded/fused together during sintering of the anode body. The bond may be a metallic bond, a covalent bond, an electrostatic bond, or the like. The sinter bonding of the wires reduces path length and resistance for current flow within the anode body, thus reducing ESR. This is particularly useful for anode bodies formed from powder of a high specific charge which tends to shrink away from the wires after sintering. The sinter-bonded wires also result in a lead assembly that is more robust and mechanically stable. |
