Aluminum electrolytic capacitors are mainly used in power supply filtering, low-frequency circuits, communication products, computers and peripheral products, instruments and meters, automation control, automobile industry, optoelectronic products, high-speed railways, aviation and military equipment.

 

Aluminum electrolytic capacitors are capacitors that use aluminum metal as an electrode, covered with an extremely thin aluminum oxide layer as a dielectric material, and have an electrolyte as a second electrode. They are commonly used in power supplies and DC-DC converters to smooth and buffer the rectified DC voltage in many electronic devices. Aluminum electrolytic capacitors are characterized by large capacity, large leakage, poor stability, positive and negative polarity, and are suitable for power supply filtering or low-frequency circuits. When using, do not connect the positive and negative poles in reverse.

 

The role of aluminum electrolytic capacitors in electronic circuits includes passing AC and blocking DC, and has the functions of filtering, bypassing, coupling and fast charging and discharging. They also have the characteristics of small size, large storage capacity and low cost. With the advancement of modern technology and the continuous improvement of capacitor performance, aluminum electrolytic capacitors have been widely used in consumer electronics, communication products, computers and peripheral products, instruments and meters, automation control, automotive industry, optoelectronic products, high-speed railways, aviation and military equipment.

 

According to the different electrolytes, aluminum electrolytic capacitors can be divided into liquid aluminum electrolytic capacitors and solid aluminum electrolytic capacitors; according to the different lead-out methods, they can be divided into three types: lead type, welding piece and welding pin type, and bolt type; according to different application fields, they can be divided into consumer aluminum electrolytic capacitors, industrial aluminum electrolytic capacitors and military aluminum electrolytic capacitors. Consumer aluminum electrolytic capacitors are mainly used in consumer markets such as televisions, audio, monitors, computers and air conditioners, while industrial aluminum electrolytic capacitors are mainly used in industrial and communication power supplies, professional inverters, CNC and servo systems, wind power generation and automobiles. ‌

 

In addition, emerging industries such as new energy, new energy vehicles, ICT, etc. have also provided new demand space for aluminum electrolytic capacitors. The high-power application scenarios in the new energy industry have a rapid growth in demand for aluminum electrolytic capacitors with high voltage levels, high ripple resistance, long life and high stability. The popularity of new energy vehicles and the construction of supporting infrastructure have also brought a vast market demand for aluminum electrolytic capacitors. In the ICT field, programmable switches, servers, routers, mobile communication base stations, etc. all require a large number of aluminum electrolytic capacitors. The growth of cloud services has spawned the demand for data center servers. The steady progress of 5G base station construction in my country will also drive the rapid growth of demand for aluminum electrolytic capacitors.
