Medium & Large Supercapacitors

Eaton Medium and Large Supercapacitors are a type of electrochemical energy storage that stores and releases electrical energy swiftly. Medium supercapacitors offer capacitance values in the range of a few hundred farads and can store moderate amounts of energy while delivering high power outputs. Large supercapacitors provide capacitance values in the range of several thousand farads, can store considerable amounts of energy, and are ideal in applications that require high power and/or long-term energy storage. Eaton Medium and Large Supercapacitors complement batteries and other energy storage technologies, making them suitable for industries requiring rapid energy storage and release.
