The Advantage Of Low
Ultra large scale integrated circuits (VLSI) development of the whole Capacitor Sustainability of the development of the industry, even by people not living among the concerns, however, since 1987, the global capacitor production over 20% annual rate of growth, so that this suspicion proved unfounded. Electrolytic capacitor has a proven strong vitality and irreplaceable. IC
one hand the emergence of some small-capacity capacitor to be integrated into the internal circuit; on the other hand, IC in the development of the circuit system frequency greatly increased, resulting in electrolytic capacitors in some circuits are other capacitors replaced. But IC circuit Power supply Some have always been inseparable from the electrolytic capacitor.
In addition, the electrolytic capacitor is also to improve their performance Other Capacitor area expansion.
Thus, electrolytic capacitors are not subject to the impact of other capacitors, and a large capacity per unit volume, static capacity, specific volume, easy miniaturization, with self-healing properties, the unique advantages of low cost. In addition, Low Although certain aspects of small-capacity competition, the way out is to accelerate the related technology research and development, strengthen and continue to expand the advantages of electrolytic capacitors available, to overcome its own shortcomings. Especially in recent years, electrolytic capacitors have achieved many significant breakthrough, achieved a qualitative leap. Not only its market share did not shrink, on the contrary, expanding its application areas, showing a high growth, ushered in a number of unprecedented opportunities for development. As one of its three major raw material products electrolytic capacitor paper with mature, low cost, environmentally friendly biodegradable, absorbable good, high temperature and other irreplaceable advantages, because some of electrolytic capacitor paper also irreplaceable.
Low voltage electrolytic capacitor paper trends
1, low loss Of the electrolytic capacitor, its loss of value depends on the intrinsic dielectric loss foil electrode and electrolyte equivalent series resistance. When the electrode foil dielectric loss inherent in a certain time to reduce the loss of key measures is to improve the electrolytic capacitor absorbent paper. Low-voltage electrolysis to improve the absorbent paper, used in most of the manufacturers are S, M, C, B, E and other loss of value of the fiber as a low voltage electrolytic paper materials, and ensure the tensile strength of paper under the premise of reducing the density of current NKK Corporation MER0.5, MR5D0.5 products have reached the density of 0.35g/cm3. In the production process, the country KAN’s S2 series was first introduced in the fiber laterally and technology, by increasing the fiber longitudinal capillary suction fluid in order to improve the paper and of the lateral suction. In the product structure, most manufacturers use double layer or multilayer composite structure reduces the value of low-voltage electrolytic paper loss, such as Japan, NKK Corporation MR5D series, our KAN’s S2, SM2, WB2 Series have adopted double-composite structure KAN China’s SMS family also adopted three composite structure.
2, high purity Electrolytic capacitor leakage current is the performance of larger defects, low-voltage electrolytic capacitors on the high precision, and therefore the leakage current have special requirements, such as high-gain pre-amplifier stage coupling capacitors require no leakage current can ensure high-fidelity stereo sound quality of the equipment, thus reducing the leakage current become to meet the requirements of this important subject. As the electrolytic electrolytic capacitor paper, the purity of the raw materials is a key factor affecting the leakage current. Currently, IEC and national standards for the purity of project indicators were varied, but well below the current actual level of electrolytic capacitor paper. Such as iron particles, the Japanese national standard 0.1 ~ 1mm2 5 / 1800cm2, the NKK Corporation of Japan and China now KAN company provides> 0.1mm2 not allowed to have, 0.08 ~ 0.1mm2 5 / 1800cm2.
3, high-intensity thin
With the electrolytic capacitor production increasing degree of automation, speed of the capacitor package volume rising strength of the electrolytic paper higher and higher demands, especially in low-voltage electrolytic capacitor paper, on the one hand, because to electrolytic capacitors to meet the requirements of low loss and small, showing the paper’s performance is to have good absorption
