With the development of the electronic information industry and the popularization of household appliances, starting from the localization of color TVs in the 1980s, refrigerators, washing machines, cassette recorders, black and white televisions, household air conditioners, telephones, energy-saving lamps VCD、DVD、 The development of computers, program-controlled switches, and other technologies has improved the quality of life for every Chinese family. The capacitor industry in our country has also experienced unprecedented development, meeting the needs of the development of electronic devices and household appliances in terms of quantity, quality, and service, and driving the development of related material, equipment, and instrument industries. It has become a major producer of capacitors worldwide.

1、 The connotation of sustainable development will be different from the past

Looking back at history, after more than 20 years of struggle, China has become a major producer of capacitors worldwide, accounting for about 30% of the total global output. Due to the global economic recovery and the rapid development of China's information industry, the capacitor industry must continue to grow while also strengthening itself. This is the core of the changing development connotation.

In the process of electronic component modularization, resistors and capacitors are at the forefront. In 2002, the chip conversion rate of resistors in Japan reached 98%, the chip conversion rate of ceramic capacitors reached 80%, and the chip conversion rate of tantalum capacitors had already reached 99% in 2001; The chip rate of resistor networks in the United States reached 41% in 2000. As for the chip conversion rate of inductors in Japan, it reached over 52% in 1998, and 70% in both Japan and the United States in 2002. The chip conversion rate of inductors used in signal circuits has reached over 80%; The switch chip conversion rate is over 20%. In 1999, the chip conversion rate of ceramic filters in Japan reached 19%, while chip ceramic filters used in cellular mobile communication devices accounted for 71%, and the chip conversion rate of temperature compensated crystal oscillators exceeded 90%.

Along with the miniaturization of electronic components, miniaturization is also rapidly developing, not only traditional components but also chip components. At present, the 1608 type chip resistive capacitive component has become the mainstream product produced in Japan, and the 1005 type chip resistive capacitive component has become the mainstream resistive capacitive component used in mobile communication devices. The minimum size of both chip tantalum capacitors and chip plastic film capacitors has reached 1608, and commercial chip ceramic capacitors and chip negative temperature coefficient thermistors (NTC) have begun mass production of the 0603 type ultra-thin products. Metallized plastic film capacitors and mica capacitors have also been commercially produced as 1608 type products.

With the thinning and miniaturization of electronic devices, the demand for composite electronic components is becoming increasingly strong. TDK Corporation in Japan has now produced monolithic ceramic capacitor arrays consisting of 4, 8, and 16 capacitor cores.

Ceramic capacitors will continue to dominate the global capacitor market, while chip capacitors will dominate the ceramic and tantalum capacitor markets. Miniaturization, large capacity, high voltage, high frequency, anti-interference and array will still be the direction of ceramic capacitor development. The 1005 type chip ceramic capacitor has become popular, the 0603 type product has been launched, and the 0402 type product is under development. At present, single stone ceramic capacitors with a capacity of up to 100 μ F have been developed using thin layer and multi-layer (600-800 layers) technology, as well as internal electrode base metal technology. Manufacturers are developing production technology for single stone ceramic capacitors with a capacity of 200 μ F or even 200 μ F or more.

Small size, large capacity, long lifespan, high temperature resistance, and low equivalent series resistance are still the development directions of aluminum electrolytic capacitors. In 2000, Panasonic Electronic Components Company developed the WA series aluminum capacitors, which increased their capacity by 2 to 18 times compared to before. At the same time, the company also introduced ultra-low profile chip aluminum capacitors with a height of only 0.95mm.

Chip products continue to lead the development of tantalum capacitors towards miniaturization, large capacity, low impedance, and low ESR. The production and application of functional polymer tantalum capacitors will further expand, and the CV value of tantalum powder will continue to increase. Currently, the CV value of tantalum powder has reached 100000, but manufacturers (such as ELNA in Japan) are already developing tantalum powder with a CV value of 150000.

It is worth noting that engineering and technical personnel are developing niobium capacitors using niobium as the dielectric material. Due to the fact that niobium supply is equivalent to 100 times that of tantalum, and the appearance, structure, and performance of this capacitor are similar to those of chip tantalum capacitors, tantalum capacitors are not suitable for mass production of 1000 μ F grade products due to cost considerations, while niobium capacitors can achieve mass production of products of this level.

2、 The market is facing new opportunities for development

New electronic whole machine systems, household appliances, communication equipment, industrial automation, etc. continue to emerge, providing new market opportunities for the development of capacitors.

The automotive electronics industry is currently the most popular industry in the international market. Traditional automotive electronization involves ten major electronic systems, including electronic instrument panel, electronic fuel injection system, automotive audio system, engine management system, global positioning system, brake anti lock system, airbag system, auto drive system, automatic window system, automatic locking system, etc. These systems all require capacitors to some extent, and higher requirements are put forward for resistance to heat, shock, ripple, low impedance, and volume and shape. In the future, electric vehicles will be the growth point of capacitors. Each electric vehicle requires at least four high-voltage and high-capacity electrolytic capacitors, which will be used in battery charging, voltage conversion, inverters and other circuits.

In terms of household appliances, including color TVs, speakers, digital cameras DVD、 Video recorders, CD players, variable frequency air conditioners, variable frequency refrigerators, washing machines, microwave ovens, rice cookers, vacuum cleaners, energy-saving lamps, etc. are all major users of capacitors. With the development of the whole machine, it is necessary to develop high-frequency, chip based, energy-saving, environmentally friendly and other products. Currently, we need to keep up with the development of products such as digital TVs, set-top boxes and digital cameras.

In the industrial field, with the increasing popularity of various automation technologies such as computer integrated manufacturing systems (CIMS), digital machining centers, and automatic assembly machines, the development of frequency conversion technology has been promoted. In the industrial field, switch mode power supplies, uninterruptible power supplies (UPS), inverters, monitors, variable frequency motors, and numerical control equipment are widely used. In addition, the capacitor industry needs to adapt to changes in laser processing, inverter motors, oil exploration, the development of third-generation and fourth generation IGBTs, and solar lighting systems for highways.

In short, it is necessary to study the market changes brought about by the rapid changes in the above-mentioned fields, do a good job in market operations, and continuously introduce products that meet different machine requirements in order to become stronger. The factors that determine the success or failure of a company, in addition to past factors such as company size, positioning, level of specialization, and market control ability, should also increase the company's response speed, flexible production capacity, resource integration capability, and innovation capability.
