Stacked foil type large-sized aluminum electrolytic capacitors

Stacked foil type of large-sized aluminum electrolytic capacitor has developed with new capacitor element construction by Nippon Chemi-Con´s. Compared to the cylinder-shaped conventional aluminum electrolytic capacitors with the same capacitance value, the stacked foil type has remarkably low ESR characteristics and high ripple current capability. For instance, the ESR reduction attains as high as approximately 60 % under a particular condition, and also it corresponds with results that were simulated with equivalent circuit model. The stacked foil type of large-sized aluminum electrolytic capacitor would be expected as filtering application for power electronics market.
