Abstract:  A capacitor and a method for assembling a capacitor. A capacitor is assembled from a case, which contains an anode that is electrically coupled to the case and defines wells or slots receiving a plurality of cathode plates. A header is placed on the case. The header also supports a glass seal that insulates the lead tube and cathode lead coming from the cathode. Once assembled, the capacitor is filled with electrolyte. A weld extends around the header to secure the header to the case. A bent cathode configuration enables a plurality of cathode plates electrically coupled together from a common cathode plate.
