The role of capacitors in electronic circuits is generally summarized as: AC and DC blocking, with the functions of filtering, bypassing, coupling and fast charging and discharging, and 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, the products have been widely used. In consumer electronic products, communication products, computers and peripheral products, instrumentation, automation control, automotive industry, optoelectronic products, high-speed rail and aviation and military equipment.

With the development of the electronic information industry and the popularization of home appliances, China's capacitor industry has achieved unprecedented development. In terms of quantity, quality and service, it has met the needs of the development of electronic complete machines and household appliances, and has driven the development of related materials industry, equipment industry, and instrument industry. It has become a The world is a major producer of capacitors, and the import of capacitors is gradually decreasing. However, some high-end products still need to rely on imports. According to the data of the prospective database, 2016year span>1-11The cumulative import volume of capacitors in my country in the month64820tons, a year-on-year decrease 6.8% .

This is2016Year1-11Monthly my country's capacitor import statistics:

my country's capacitor products are still mainly low-end and medium-grade, and many Products are still heavily dependent on imports. my country's capacitor industry is not only a major producer in the world, but also a major exporter, but the products are still mainly low-end products. The main problems currently faced are: my country's domestic production of electronic materials, spare parts, instruments and other upstream products for the capacitor manufacturing industry. Compared with the world's advanced level, there is still a gap, and many products still rely heavily on imports. This has become a major problem restricting the development of my country's capacitor manufacturing industry.

With the rapid development of the whole machine market, especially mobile communications, etc. Development, the requirements for high frequency, high temperature, high voltage, miniaturization, etc. of capacitors are getting higher and higher. Under the guidance of national medium and long-term planning, and driven by the development of a new generation of information technology, enterprises must accelerate the upgrading of industrial structure and enhance independent innovation. Ability and comprehensive competitiveness, realize the transformation of the capacitor industry from large to strong, and become a global capacitor production power.
