The huge development prospect of film capacitor

With the global promotion of low-carbon environmental protection and green travel, the development of new energy electric vehicles is becoming more and more rapid. The proportion of traditional aluminum electrolytic capacitors is decreasing, and the more advanced and environmentally friendly film capacitors are gradually on the stage of the times.

As a basic electronic component, film capacitors are widely used in lighting, household appliances, automobiles, and new energy fields such as solar energy and wind energy. The lighting field is the main business area of most domestic manufacturers. In 2015, the market size of only thin film capacitors for fluorescent lamp rectification was as high as 3.5 billion yuan, equivalent to 22% of the total size of the global film capacitor market. Since 16 years ago, as LED technology has become more and more mature, more and more fluorescent lamps have been replaced by LED light sources, and since the amount of film capacitors in LED lamps is very small, almost all LEDs of 8W or more are used. The field of film capacitors began to shrink.

The global film capacitor industry continues to expand, and China has become a dominant force. According to the statistics of the China Electronic Component Industry Association Information Center, the global production of film capacitors is mainly concentrated in Europe, America, China, Japan, South Korea, Taiwan and other regions. With the rapid development of China's economy and global procurement, the output value of China's film capacitor market in 2017 was about 1.3 billion US dollars, accounting for 42% of the global market's total output value, ranking first in the world.

According to statistics, in 2016, the largest regional market for film capacitors in China was in East China, with an output value of 4.14 billion yuan, accounting for 48.75% of the total market. In addition, the output value of South China and Northeast China reached 1.44 billion yuan and 1.14 billion yuan respectively. On the whole, the regional distribution of China's film capacitor industry is very uneven. The total proportion of North China, Northwest China and Southwest China is only about 11%, while East China and South China account for about 65%, and industrial concentration is high.

The development prospect of film capacitors is still huge, because it has the advantages of non-polarity, high withstand voltage, wide frequency response, and good temperature characteristics. It is widely used in converter, inverter, inverter and other converter circuits, and is widely used by various manufacturers. Love.
