Looking back in history, after 20 years of struggle, China has become the biggest producer of global capacitor. 30% of the world's total output. Due to the global economic recovery and China's rapid development of the information industry, in the capacitor industry to continue to be strong at the same time. to build up, it changes the meaning of the development is the core.
Chip in the process of electronic components, resistors and capacitors lead. 2002, the Japanese chip resistors rate reached 98%, 80% rate of ceramic chip capacitors. Tantalum chip capacitors rate has already reached 99% in 2001 Chip resistor network in the United States the rate of 41% in 2000. As Chip Inductors rate has reached more than 52% in Japan in 1998, 2002, the United States has already achieved a 70% Signal Circuits and Chip Inductors the rate has reached more than 80%. Switch Chip rate of over 20%. 1999 Japanese ceramic filter chip rate as high as 19%. and the use of cellular mobile communication equipment accounted for 71% of chip ceramic filter.
Chip TCXOs rate has been over 90%. Electronic components in the chip at the same time, the miniaturization is also growing rapidly, not only in the traditional rapid miniaturization of components, miniaturize chip components is also growing rapidly. At present, 1,608-film resistor and capacitor production in Japan has become a mainstream product. 1005-film resistor and capacitor has become the mainstream of mobile communications equipment using resistor and capacitor. Tantalum chip capacitors and chip has already achieved a minimum size plastic film capacitors 1608, and have been commercialized. Ceramic chip capacitors, Chip resistor negative temperature coefficient (NTC) has started small-batch production 0,603 products metallized plastic film capacitors and mica capacitors 1608 products have been commercial production.
With thin small in the electronic equipment, electronic components on the complex requirements become stronger and stronger. Japanese TDK company is the production of core components by scanning capacitors array of Monolithic Ceramic Capacitors. Ceramic Capacitors will capacitors in the world market dominating position. Chip capacitors and ceramic capacitors and tantalum capacitors will dominate the market. Small, large capacity, high voltage, high frequency interference and array of ceramic capacitors will continue to be the direction of development. 1005-ceramic chip capacitors has been popular, has listed 0,603 products, 0,402 products in development. Currently, the use of TLC and multi-level (600-level dosage level) within the technology and base metal electrode technology have developed a capacity of 100 μg F Monolithic Ceramic Capacitors. The manufacturer has in the development of capacity for 200 or 200 μg ± F F above Monolithic Ceramic Capacitors production techniques.
Small size, large-capacity, long-life, resistance to high temperature, low equivalent series resistance of electrolytic capacitors is the direction of development. 2000 Matsushita Electronic Components has developed a series of aluminum capacitors WA. increase its capacity by two-fold to 18-fold compared with the previous same time, the company has invested a low-film appearance of aluminum capacitors, its only 0.95mm high. Chip tantalum capacitor products continue to lead to smaller, high-capacity, low-impedance, low ESR direction. Production and application of functional polymer tantalum capacitors will be further expanded, and will continue to improve CV tantalum powder.
CV tantalum powder now reached 100,000. But manufacturers (such as Japan ELN) has 150000CV value in the development of tantalum powder. It is noteworthy is the development of engineering and technical personnel for the use of niobium capacitor dielectric material niobium, Nb-Ta because the supply is equivalent to 100 times that of the capacitor configuration, structure and properties of tantalum chip capacitors and similar Due to cost, tantalum capacitor was unsuitable 1000 F-class products in large quantities. Niobium capacitors can be realized and the magnitude of the mass-produced products.
