Abstract
An aluminum electrolytic capacitor has a wound extended-foil section with the edges of one of the foils extending from one edge of the roll and the edges of the other from the other edge. These extended foils are deformed after the section is wound in such a way that they are stretched and a metallurgical bond is formed between adjacent edges. A low-inductance, low electrical series resistance (ESR) capacitor is obtained as a result. The deformation may be accomplished by frictional cutting using a diamond saw.
