ELECTROLYTIC ALUMINIUM CAPACITORS

The dielectric consists of a metal oxide generated by electro-chemical
treatment of a very pure aluminium foil (anode). A liquid electrolyte
ensures the connection with the other metal plate (cathode).
Electrolytic aluminium capacitors are the most efficient as far as capacitance
vs. volume are concerned. Due to their characteristics and polarisation,
their fields of application are basically limited to filtering and
energy storage. Their usage in frequency is limited.
