Classification of capacitors

Capacitors are components that store electricity and electrical energy (potential energy). the classification of capacitors is 10 categories. 1. The classification of capacitors is divided into three categories according to the structure: fixed capacitors, variable capacitors and trimmer capacitors. 2. Classified by electrolyte: organic dielectric capacitor, inorganic dielectric capacitor, electrolytic capacitor, electric heating capacitor and air [...]

The principle and application of electrolytic capacitors

Electrolytic capacitors are usually made of metal foil (aluminum/tantalum) as the positive electrode, and the insulating oxide layer of the metal foil (aluminum oxide/tantalum pentoxide) as the dielectric. Electrolytic capacitors are divided into aluminum electrolytic capacitors and tantalum electrolysis based on their positive electrodes. Capacitors. The negative electrode of an aluminum electrolytic capacitor is composed of [...]

The difference between solid capacitors and electrolytic capacitors

Solid capacitor full name solid aluminum electrolytic capacitor, the difference between solid capacitors and electrolytic capacitors is mainly the following points: 1. Different dielectric materials are used. The liquid aluminum capacitor dielectric material is electrolyte, while the solid capacitor dielectric material is conductive polymer. 2. Overheating of the electrolytic capacitor will cause the electrolyte to expand [...]
