3. Characteristics of Super Capacitor
Super Capacitor can not be used for applications in AC circuit such as ripple absorption because it has high internal resistance
(several hundred mΩ to a hundred Ω) compared to aluminum electrolysis capacitor. Thus its main use would be similar to that
of secondary battery such as power back-up in DC circuit. The following list shows the characteristics of Super Capacitors as
compared to aluminum electrolyses capacitors for power back-up and secondary batteries.

(*1) Aluminum electrolysis capacitor and Super Capacitor has limited lifetime. However, when used under proper conditions, both can operate
sufficiently within the designed lifetime of the set they are built in.
(*2) There is no harm as it is a mere leak of water vapor which transitioned from water contained in the electrolyte (diluted sulfuric acid).
However, application of abnormal voltage surge exceeding maximum operating voltage may result in leakage and explosion.
