The engineer''s guide to aluminum electrolytic capacitors
Aluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V). These polarized capacitors usually have a wide tolerance (± 20%), tend to exhibit large leakage currents (5 to 20 µA per µF), and have low self-resonant frequency (f RES < 100 kHz).

Aluminum Electrolytic Capacitors
An Aluminum Electrolytic Capacitor is a type of capacitor that contains just a few essential parts: aluminum foil, electrolytic paper, an aluminum oxide layer, and two terminals (a cathode and an anode). Aluminum Electrolytic Capacitors work by using the polarity between the two terminals to maintain high capacitance within the component.

Principles: Aluminum electrolytic capacitors | ELNA CO., LTD.
Aluminum electrolytic capacitors are made by layering the electrolytic paper between the anode and cathode foils, and then coiling the result. The process of preparing an electrode facing the etched anode foil surface is extremely difficult. Therefore, the opposing electrode is created by filling the structure with an electrolyte.

The modern era of aluminum electrolytic capacitors
The first article in this series [1] covered the early history of electrolytic capacitors, from their invention around 1880 to the invention of the modern Al electrolytic capacitor structure in 1925. To summarize the early history, "valve metals" were recognized in the 1880s for their ability to conduct in one direction but impede current flow in the …
