What is an Aluminum Electrolytic Capacitor? Also called an electrolytic capacitor, this capacitor uses liquid electrolyte as the role of cathode and aluminum oxide as dielectric. It features a large capacitance by forming minute unevenness on the surface of aluminum foil through electrochemical treatment to enlarge the surface area.
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in …
Aluminum electrolytic capacitors are made of two aluminum foils and a paper soaked in electrolyte. The anode aluminum foil is anodized to form a very thin oxide layer on one side and the unanodized aluminum acts as cathode; the anode and cathode are separated by paper soaked in electrolyte, as shown in Fig. 8.10A and B.The oxide layer serves as a dielectric and …
