Characteristics of electrolytic capacitors and tantalum capacitors

1. Disadvantages of electrolytic capacitors Because of its large capacity and low price, it is widely used in rectifier and filter circuits. The heating of electrolytic capacitors can accelerate the consumption of electrolyte and dry up, and even cause the electrolyte to boil and burst the slurry. At the same time, the drying of the electrolyte [...]

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 [...]
