What are electrolytic capacitors?

Electrolytic capacitors are a type of capacitor that can have much larger levels of capacitance than many other types. Electrolytic capacitors use an electrolyte which is a liquid or gel that contains a high concentration of ions.

How do electrolytic capacitors work?

Electrolytic capacitors use a chemical feature of some special metals, previously called "valve metals", which on contact with a particular electrolyte form a very thin insulating oxide layer on their surface by anodic oxidation which can function as a dielectric. There are three different anode metals in use for electrolytic capacitors:

Why are electrolytic capacitors better than other types of capacitors?

Electrolytic capacitors possess a very wide tolerance. They are relatively cheaper when compared to other types of capacitors with similar capacitance values. It helps in quick charging and discharging. Minimal maintenance is required for proper functioning. Electrolytic capacitors have self-healing capability.

What are the disadvantages of electrolytic capacitors?

Large leakage currents, tolerance levels are high and limited lifecycles are some of the disadvantages that come with electrolytic capacitors. Definition – A electrolytic capacitor is a type of capacitor that uses an electrolyte that can achieve a much large capacitance value than many other capacitor types. They are polarized capacitors.

Which electrolytic capacitor has a lifetime specification?

However, solid polymer electrolytic capacitors, and aluminium, tantalum, and niobium electrolytic capacitors also have a lifetime specification. The polymer electrolyte exhibits a small deterioration of conductivity caused by thermal degradation of the conductive polymer.

Why do electrolytic capacitors have a high capacitance value?

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.
