What is the electric field strength of aluminum electrolytic capacitor?

An aluminum electrolytic capacitor has an electric field strength of the dielectric oxide film of approximately 600kV / mm during operation, which is more than 30 times that of paper dielectric capacitors.

Why do electrolytic capacitors have a high field strength?

The reason that electrolytic capacitors have such uniform dielectric stress and can operate at such high field strength, within 80% of their breakdown strength, on the order of 1,000 volts / µm, is due to two reasons.

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.

How do electrolytic capacitors store energy?

Like other conventional capacitors, electrolytic capacitors store the electric energy statically by charge separation in an electric field in the dielectric oxide layer between two electrodes. The non-solid or solid electrolyte in principle is the cathode, which thus forms the second electrode of the capacitor.

Do electrolytic capacitors have a high volumetric capacitance?

The dielectric thickness of electrolytic capacitors is very small, in the range of nanometers per volt. On the other hand, the voltage strengths of these oxide layers are quite high. With this very thin dielectric oxide layer combined with a sufficiently high dielectric strength the electrolytic capacitors can achieve a high volumetric capacitance.

What are the advantages of electrolytic capacitors?

The advantage of electrolytic capacitors is the high capacitance per unit volume and per unit cost. The high capacitance arises from the high dielectric constant, the high breakdown field strength, the rough surface, and the extremely small, uniform thickness of the anodically formed metallic oxide.
