China solid-state capacitors industry present situation analysis
Solid-state capacitors as growth better capacitor products, has a good application prospect. Solid-state capacitors with high conductivity and good thermal stability of polymer materials to replace traditional electrolyte, compared with the ordinary liquid aluminum electrolytic capacitor has high reliability and long service life, high frequency, low impedance, knight large ripple current features, every alternative 2 - solid capacitor Three common aluminum electrolytic capacitor, which is beneficial to the integration and miniaturization of electronic products, and can overcome the liquid aluminum electrolytic capacitor leakage easily and so on. In notebook computers, LCDTV, 3 d display, game consoles, and other fields has a huge market space.
With the development of 4 g networks, electronic information industry and the consumption structure upgrade, especially as its core raw material price drop, solid-state capacitor applications will continue to expand, the market demand is growing rapidly. Many advantages compared with liquid capacitor as the three passive electronic components ( Resistance, capacitance and inductance) One of the capacitor is very important in the electronic components industry, is the foundation of the electronic circuit of electronic components. In the whole machine use electronic components, capacitor USES the most extensive, most consumable, accounts for about 40% of the total dosage of electronic components. Capacitor with a variety of dielectric materials, can be divided into aluminum/tantalum electrolytic capacitors, ceramic capacitors, film capacitors, paper condenser, mica capacitor etc. , including aluminum/tantalum electrolytic capacitors, ceramic capacitors and film capacitor these three accounts for about capacitor over 90% of the total market.
Aluminum electrolytic capacitor from different electrolyte can be divided into liquid aluminum electrolytic capacitor and solid aluminum electrolytic capacitor, the different methods of liquid aluminum electrolytic capacitor according to elicit can be divided into type, welding and welding lead pin type, screw type 3 kinds. Solid aluminum capacitor with high electric conductivity and thermal stability of conductive polymer materials instead of electrolyte, compared with the ordinary liquid aluminum electrolytic capacitor, has high reliability and long service life, high frequency, low impedance, knight large ripple current characteristics, and is conducive to the integration and miniaturization of electronic products and can overcome the disadvantages of liquid aluminum electrolytic capacitor leakage easily.
In solid aluminium electrolytic capacitor cost effective drop of background, the future of solid aluminum electrolytic capacitor application should be more and more.
Electrode foil is the most important basic raw materials solid capacitor electrode foil is the most important basic raw materials, electrode foil used for carrying charge, 30% of the cost of capacitor production -
Electrode foil production mainly through two processes, namely, corrosion and into, is the incomplete form of electrode foil, foil after into working procedure, which is a product of electrode foil form, also known as the foil, as the raw material of solid capacitor directly.
Solid-state capacitors industry technology development trend of electronic device miniaturization, lightweight development trend puts forward higher requirements on the performance of the solid-state capacitors, the main technology development trend are: high temperature resistant, long life, high reliability;
Environmental protection, etc.
The electrode foil which makes high volume, high voltage direction.
