6 FAQs about [Electrolytic capacitor dielectric type]
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.
What is a dielectric material in a capacitor?
The dielectric material is produced from the anode metal itself through the process of anodization. So formed dielectrics are aluminum oxides, tantalum pentoxide, and niobium pentoxide respectively. The electrolyte of the capacitor can be solid, liquid or gel. This electrolyte covers the oxide layer and acts as the cathode.
