Dingfeng Capacitor-- Introduction to aluminum electrolytic capacitors

Issue Time:2019-06-17

At present, the global aluminum electrolytic capacitor supply market is becoming more and more mature, mainly concentrated in Japan, China, South Korea and other regions. Judging from the overall competitive landscape of the industry in recent years, the production of electrolytic capacitors in Japan has begun to shrink and reduce production. Instead, Korean companies and Chinese companies are replaced. Aluminum electrolytic capacitors were considered high-tech products in China before 1978. After more than 30 years of development, China's capacitors have completely replaced foreign capacitors.

The basic role of aluminum electrolytic capacitors in electronic circuits is generally summarized as: AC and DC. It has the functions of filtering, bypassing, coupling and fast charging and discharging. It has the characteristics of small size, large storage capacity and high cost performance. Aluminum electrolytic capacitors have been widely used in consumer electronics, communications products, computers and peripheral products, new energy, automation control, automotive industry, optoelectronic products, high-speed rail and aviation and military equipment.

Aluminum electrolytic capacitors can be classified into liquid aluminum electrolytic capacitors and solid aluminum electrolytic capacitors depending on the form of the electrolyte. According to the different methods of lead-out, it can be divided into five types: lead type, soldering type, soldering type, bolt type, and patch type.


Aluminum electrolytic capacitors are classified into aluminum electrolytic capacitors for consumer, industrial and special applications, depending on the application. Consumer aluminum electrolytic capacitors are mainly used in consumer markets such as energy-efficient lighting, televisions, displays, computers and air conditioners. Industrial aluminum electrolytic capacitors are mainly used in industrial and communication power supplies, professional inverters, numerical control and servo systems, wind power generation and automotive industries. Special aluminum electrolytic capacitors are mainly used in military, aerospace and other special fields.
