Supercapacitors – FA Series
Performance Characteristics
Supercapacitors should not be used for applications such as ripple absorption because of their high internal resistance (several
hundred mΩ to a hundred Ω) compared to aluminum electrolytic capacitors. 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 supercapacitors as compared to aluminum
electrolytic capacitors for power back-up and secondary batteries.

Safety Risks

leakage, combustion,
explosion, ignition
heat-up, explosion
gas emission (*2)
(*1) Aluminum electrolytic capacitors and supercapacitors have limited lifetime. However, when used under proper conditions, both can operate within a
predetermined lifetime.
(*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.
