An electrolytic capacitor is a polarized capacitor that utilizes an electrolyte to achieve a larger capacitance than other capacitor types. These are often used when high-charge storage is required in a small volume. In this article, we will discuss their classification, construction, and uses. What is an electrolyte? What is an electrolyte?
The rated voltage range of these capacitors is from approximately 120 V AC (capacitive lighting ballasts) to 100 kV. Electrolytic capacitors have a metallic anode covered with an oxidized layer used as dielectric.
Electrolytic capacitors have a metallic anode covered with an oxidized layer used as dielectric. The second electrode is a non-solid (wet) or solid electrolyte. Electrolytic capacitors are polarized. Three families are available, categorized according to their dielectric.
Film and paper capacitors are named for their dielectrics. Silver mica, glass, silicon, air-gap and vacuum capacitors are named for their dielectric. In addition to the above shown capacitor types, which derived their name from historical development, there are many individual capacitors that have been named based on their application.
The electrolyte of the capacitor can be solid, liquid or gel. This electrolyte covers the oxide layer and acts as the cathode. Due to this enlarged anode surface and very thin dielectric oxide layer, electrolytic capacitors can have a high capacitance voltage per unit volume. Hence they can have a high capacitance value.
These are primarily aluminum electrolytic capacitors, and tantalum as well as some film capacitors and Class 2 ceramic capacitors. Aluminum electrolytic capacitors, the most common type for power supplies, experience shorter life expectancy at higher ripple currents.
