What is aluminum electrolytic capacitor?

1. General Description of Aluminum Electrolytic Capacitors An aluminum electrolytic capacitor consists of cathode aluminum foil, capacitor paper (electrolytic paper), electrolyte, and an aluminum oxide layer, which acts as the dielectric, formed on the anode foil surface.

What are electrolytic capacitors made of?

Electrolytic capacitors are normally made from one of three different materials: aluminum, tantalum, and niobium. Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons:

What is the anode of an aluminum electrolytic capacitor?

The anode of an aluminum electrolytic capacitor is an aluminum foil of extreme purity. The effec-tive surface area of this foil is greatly enlarged (by a factor of up to 200) by electrochemical etch-ing in order to achieve the maximum possible capacitance values.

What is the dielectric layer of an aluminum electrolytic capacitor?

The dielectric layer of an aluminum electrolytic capacitor is created by anodic oxidation (forming) to build up an aluminum oxide layer on the foil. The layer thickness increases in proportion to the form-ing voltage at a rate of approximately 1.2 nm/V.

What types of aluminum electrolytic capacitors are not covered?

Other types of aluminum electrolytic capacitors not cov-ered include the obsolete wet types without separator mem-branes, “hybrid” aluminum electrolytic capacitors containing both polymer and liquid electrolyte components and sol-id-polymer electrolytic capacitors.

What is an electrolytic capacitor?

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
