What is an electrolytic capacitor?

1、 Definition and Structure of Electrolytic Capacitors
Electrolytic capacitor, as the name suggests, is a type of capacitor made using the principle of electrolysis. Its basic structure includes two electrodes (positive and negative) and an electrolyte. Unlike ordinary capacitors, the electrodes of electrolytic capacitors usually use aluminum foil or tantalum foil as the anode, while the cathode is a layer of oxide film or conductive polymer. Electrolyte is filled between the two poles, playing a dual role of isolation and conductivity.
2、 The working principle of electrolytic capacitors
The working principle of electrolytic capacitors is based on the storage and release of charges. When a voltage is applied across the capacitor, the aluminum foil on the positive electrode loses electrons to form a positive charge, while the oxide film or conductive polymer on the negative electrode attracts electrons to form a negative charge. These charges are stored inside the capacitor under the action of electric field force, forming an electric field. When external circuits require energy, capacitors quickly release stored charges to provide the required current for the circuit.
3、 Characteristics and advantages of electrolytic capacitors
Large capacity: Electrolytic capacitors have extremely high capacitance values and can store a large amount of charge, meeting high energy demand applications.
High voltage: capable of withstanding high operating voltages, suitable for high-voltage circuits.
Low cost: Compared with other types of capacitors, electrolytic capacitors have lower production costs and more affordable prices.
Long lifespan: Under normal working conditions, the lifespan of electrolytic capacitors can reach several years or even longer.
4、 Application fields of electrolytic capacitors
Electrolytic capacitors have a wide range of applications in the field of electronics due to their unique properties. They are widely used in power filtering, energy storage, signal coupling, decoupling, and AC signal bypass. Electrolytic capacitors play a crucial role in fields such as new energy vehicles, smart grids, communication equipment, and computers. They not only improve the performance and stability of electronic devices, but also drive technological progress and development.
