With the country’s increased investment in smart grid construction, electrified railroad construction and new energy (automotive, wind power, photovoltaic), as well as the upgrading of consumer electronics, industrial control technology continues to advance, snubber film capacitors market can grasp the opportunity to ride the wind? Recent professional organizations predict that the high-end film capacitor market is expected to grow steadily in the next few years.
Snubber Film Capacitors Industry Overview
Snubber film capacitors refer to the capacitor with electrical grade plastic film as dielectric and metal foil as electrode, which has the advantages of wide temperature range, long service life, strong self-healing function, high withstand voltage, no polarity, and good frequency characteristics, etc. It is suitable for analog circuits with a certain amount of power, especially in the part of the signal cross-linking, which needs to be used in capacitors with good frequency characteristics and very low dielectric loss. Film capacitors, as basic electronic components, are widely used in lighting, household appliances, automobiles, and new energy fields such as solar energy and wind energy.
Snubber film capacitors are key devices in new energy vehicle motor control and photovoltaic wind power inverters. Compared with aluminum electrolytic capacitors, film capacitors have high withstand voltage, self-healing function, no polarity, high-frequency characteristics, long life, etc., more in line with the requirements of the new energy vehicles, with the future market demand for new energy vehicles, film capacitors market will be more broad.
With the introduction of a series of national policies to encourage the new energy automobile industry, the global government ban on the sale of fuel vehicles planning, foreign automotive giants of the new energy plan to continue to promote the superimposed technology upgrades, scale effect and the use of convenient, new energy vehicle sales outbreak led to the film capacitor demand for high growth. 2021, China’s new energy vehicle sales amounted to 3,334,100, an increase of 167.64%. 167.64%, and is expected to grow further to 4,654,300 units in 2022. China is the world’s largest new energy vehicle market, with the support of various policies, the new energy vehicle market has achieved rapid development, and has a high brand recognition and perfect service system of film capacitors industry leader will obviously benefit.
In the field of wind power photovoltaic, film capacitors can be used in wind power converters and photovoltaic inverters, the same capacity under the characteristics of high throughput capacity so that it gradually replace the aluminum electrolytic capacitors, the future will further expand the proportion of its use. PV inverter is one of the core components of PV system in solar power generator set, which needs to meet different functional requirements, not only to ensure the conversion of DC/AC, but also need to ensure the quality of the output power, film capacitors have been widely used in PV inverters with its excellent and stable performance and long-term reliable life. Under the “double carbon” strategy, the PV industry has a broad prospect, fierce competition and strong development momentum. In recent years, China’s cumulative installed capacity of photovoltaic power generation has maintained growth. As of July 2022, China’s cumulative installed capacity of PV power generation was 343.51 million kilowatts, a year-on-year increase of 26.7%. Film capacitors in photovoltaic equipment penetration rate has been nearly 100%, every 1GW of new energy installed capacity needs 20 million yuan worth of film capacitors, high-quality film capacitors market development prospects are optimistic.
Industry Competitive Landscape
- Global Competitive Landscape
Snubber film capacitors global market competition pattern is decentralized, from a global point of view, the main manufacturers include Japan’s Panasonic, Nichicon and TDK-EPCOS, the U.S. KEMET (acquired by China Taiwan’s National Giant in 2020) and Vishay, as well as some of the domestic leading enterprises. High-voltage high-capacity film capacitors for high-end products, high technical barriers, high value-added, the core technology are mastered by the international leading enterprises, the market in this field to Japan, Europe and the United States manufacturers as the dominant, on behalf of the enterprise for the Japanese Nichicon, Panasonic, the United States based on the United States. Medium-low voltage and low-voltage film capacitors are more mature, the popularity of manufacturing technology is high, many market participants, competition is fierce. Chinese enterprises have cost advantages in this field, the competitive pattern in this field is the situation of Chinese and Japanese enterprises competing. - Domestic competition pattern
At present, China’s snubber film capacitors industry has a low degree of industrial concentration, and there are more than 100 large-scale film capacitor manufacturers in mainland China. Domestic film capacitors as the main business of the listed companies / New Third Board companies have the advantage of scale, while unlisted film capacitor companies in addition to some national specialties and new “small giants” enterprises, such as seven star electronics, generally smaller, and the number of enterprises, the level of uneven, mainly supporting the traditional home appliances and lighting market, the market competition is fierce. Market competition is fierce.
Industry Barrier
- Capital Barriers
Snubber film capacitors manufacturing industry production needs to continue to invest in equipment and capital, capital-intensive features. Film capacitor manufacturers to ensure their profit margins, need to reach a certain scale of production, the use of economies of scale to achieve profitability. At the same time, the film capacitor production process through a number of procedures, the size of the enterprise’s equipment, production sites and other large capital investment. Therefore, the film capacitor industry has a certain financial barriers. - Market entry barriers
The global film capacitor industry is characterized by sufficient competition and strong brand effect of head enterprises. At present, the capacitor industry has entered a stable growth stage, after full competition in the industry, domestic and foreign famous film capacitor brands also stand out, occupy the main global market. - Technical barriers
Snubber film capacitors for technology-intensive industries, and different varieties of capacitors manufacturing process is different, companies not only need to fully grasp the mechanical, electrical, information and other complexity of the technology, but also with the development of new models, program design, precision parts processing and other comprehensive capabilities, in order to provide customized services for different customers. - Access to downstream customer barriers
Enterprises selling products need to obtain downstream customer certification, and new energy, photovoltaic wind power and other areas of the capacitor enterprise certification cycle is long. Traditional home appliances and lighting field customer certification cycle within 1 year, while the new energy, industrial control field customer certification cycle of 2-3 years. Longer certification cycle is not conducive to the development of the market, access to downstream customers.
