摘要:
A method of joining a connection member to a capacitor foil using a staking tool having a tip of less than 0.030″ (0.762 mm) in diameter. Another embodiment couples multiple connection members of a capacitor together by edge-connecting each connection member to its substantially flush neighboring connection members. In one aspect, a capacitor includes a multi-anode stack connected at a first weld by a weld joint less than 0.060″ (1.524 mm) in diameter and a tab attached to one of the anodes of the multi-anode stack at a second weld. In one aspect, an exemplary method joining one or more foils using a staking tool having a tip of less than approximately 0.060″ (1.524 mm) in diameter. In another aspect, a capacitor including a capacitor case having an electrolyte therein and a high formation voltage anode foil having a porous structure and located within the capacitor case.
