| Pan Danan, Secretary General of capacitor branch of China Electronic Components Industry Association With the development of electronic information industry and the popularization of home appliances, the development of refrigerators, washing machines, tape recorders, black-and-white TV sets, household air conditioners, telephones, energy-saving lamps, VCD, DVD, computers, program-controlled switches, etc., has improved the quality of life of every Chinese family. China's capacitor industry has also been unprecedentedly developed. In terms of quantity, quality and service, it meets the needs of the development of the above-mentioned electronic machines and household appliances, and drives the development of the relevant material industry, equipment industry and instrument industry, and has become a major producer of capacitors in the world. The connotation of sustainable development will be different from that in the past. After more than 20 years of struggle, China has become a major producer of capacitors in the world, 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 be stronger while continuing to grow bigger, which is the core of the change of development connotation. In the process of chip electronic components, resistors and capacitors take the lead. In 2002, the chip rate of resistor in Japan was 98%, that of ceramic capacitor was 80%, that of tantalum capacitor was 99% in 2001, and that of resistance network in America was 41% in 2000. As for the chip rate of inductors in Japan in 1998, it has reached more than 52% in 1998, and 70% in Japan and the United States in 2002, while the chip rate of inductors for signal circuits has reached more than 80%, and the chip rate of switches has reached more than 20%. In 1999, the chip rate of ceramic filters in Japan reached 19%, while 71% of the ceramic filters used in cellular mobile communication equipment, and the chip rate of temperature compensated crystal oscillator exceeded 90%. At the same time, the miniaturization of electronic components is also developing rapidly. Not only the traditional components are rapidly miniaturized, but also the chip components. At present, 1608 chip resistance and capacitance components have become the mainstream products produced in Japan, and 1005 chip resistance and capacitance components have become the mainstream resistance and capacitance components used in mobile communication equipment. The minimum size of chip tantalum capacitor and chip plastic film capacitor have reached 1608 and have been commercialized. Chip ceramic capacitors, chip negative temperature coefficient thermistors (NTC) have begun to produce 0603 type miniature products in batch, metallized plastic film capacitors and mica capacitors have been commercialized to produce 1608 products. With the development of electronic equipment, the demand of electronic components is becoming more and more intense. TDK company of Japan has produced monolith ceramic capacitor array composed of 4,8,16 capacitor cores. Ceramic capacitors will still dominate the world 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 development direction of ceramic capacitors. Type 1005 chip ceramic capacitor has been popular, 0603 product has been on the market, 0402 product has been developed. At present, monolith ceramic capacitors with capacity up to 100 μ F have been developed by using thin layer and multilayer (600-800 layer) technology and inner electrode base metal technology. Manufacturers have been developing the manufacturing technology of monolith ceramic capacitors with capacity of 200 μ f or even more. Small size, large capacity, long life, high temperature resistance and low equivalent series resistance are still the development direction of aluminum electrolytic capacitors. In 2000, Panasonic electronic components company developed wa series aluminum capacitors, the capacity of which was increased by 2-18 times compared with the previous ones. At the same time, the company also put in chip aluminum capacitors with ultra-low profile, whose height is only 0.95mm. Chip products continue to lead tantalum capacitors to miniaturization, large capacity, low impedance and low ESR. The production and application of functional polymer tantalum capacitors will be further expanded, and the CV value of tantalum powder will continue to increase. At present, the CV value of tantalum powder has reached 100000, but manufacturers (such as Elna company of Japan) have been developing tantalum powder with 150000 CV value. It is worth noting that engineers and technicians are developing niobium capacitors using niobium as dielectric material. Because the supply of niobium is 100 times of that of tantalum, and the appearance, structure and performance of the capacitor are similar to those of chip tantalum capacitor. Due to the cost, tantalum capacitor is not suitable for mass production of 1000 μ F grade products, and niobium capacitor can realize the mass production of such products.The market is facing new opportunities for development. New electronic systems, household appliances, communication equipment, industrial automation and so on are emerging, which provide new market opportunities for the development of capacitors. The automotive electronics industry is the most popular industry in the international market. The traditional automotive electronics involves ten major electronic systems, including electronic dashboard, electronic fuel injection system, car audio system, engine management system, global positioning system, ABS, airbag system, automatic driving system, automatic window system, automatic lock system and so on. Capacitors are more or less used in these systems, and higher requirements are put forward for heat resistance, shock resistance, ripple resistance, low impedance and volume shape. In the future, electric vehicles are the growth point of capacitors. Each electric vehicle needs at least 4 electrolytic capacitors with high voltage and large capacity, which are used in battery charging, voltage conversion, inverter and other circuits. In terms of household appliances, color TV, stereo, digital camera, DVD, VCR, CD player, variable frequency air conditioner, variable frequency refrigerator, washing machine, microwave oven, rice cooker, vacuum cleaner and energy-saving lamp are all major users of capacitors. With the development of the whole machine, it is necessary to develop high-frequency, chip, energy-saving and environmental protection products, and to keep up with the development of digital TV, set-top box and digital camera. In the industrial field, with the development of computer integrated manufacturing system (CIMS), digital machining center, automatic assembly machine and other automation technologies, the development of frequency conversion technology is promoted. Switching power supply, uninterruptible power supply (UPS), inverter, monitor, variable frequency motor, numerical control equipment are widely used in the industrial field. In addition, laser processing, inverter motor, oil exploration, the development of the third and fourth generation IGBT, and the solar lighting system of expressway are widely used. The capacitor industry should adapt to its changes. In a word, it is necessary to study the market changes brought about by the rapid changes of the whole machine in the above fields, do a good job in the market operation, and constantly introduce products that meet the requirements of different complete machines. The factors that determine the success or failure of an enterprise are not only the enterprise scale, positioning, specialization level, market control ability, but also the reaction speed, flexible production capacity, resource integration ability and innovation ability.
