Detailed Product Description：	Yada Kang Electronics: committed to providing the world with superior quality aluminum electrolytic capacitors Yada Kang electronic equipment manufacturing of aluminum electrolytic capacitor electrode foil production and marketing and capacitors as the main business scope. Yada Kang electronics company is committed to providing the world with superior quality aluminum electrolytic capacitors and in nearly 20 years of the development process, Yada Kang electronic continuous technological research and development, continuous improvement and development of new products, constantly enhance the capability of independent innovation, and gradually establish a corrosion of the electrode foil and into technology, core technology modules electrolyte technology, manufacturing technology of aluminum electrolytic capacitors, aluminum electrolytic capacitor production equipment, manufacturing technology and capacitor quality management, software development technology based on the whole industry chain of aluminum electrolytic capacitors, formed Yada Kang Electronic unique core competitiveness. Yada Kang electrons from the aluminum electrolytic capacitor series of early production lead consumer electronic products to the consumer of aluminum electrolytic capacitors, industrial aluminum electrolytic capacitor aluminum electrolytic capacitor-based energy-efficient lighting class, covering the full range of products; in accordance with the appearance of the product structure Yada Kang electronic products, the current welding stylus, lug type, bolt type, lead type, chip and solid aluminum electrolytic capacitors. Yada Kang electronic products are widely used in energy-efficient lighting products, consumer electronics, communications, automotive electronics, industrial applications and other fields. At present, Japan, Taiwan, South Korea and mainland China is the main producing countries and regions of the world's aluminum electrolytic capacitors, the world's top five aluminum electrolytic capacitor manufacturers, four Japanese companies, namely: Chemi-con, Nichicon, Rubycon and Panasonic. In recent years, Japanese companies due to high production costs, can not compete with low-priced products in Taiwan and South Korean companies, has started closing factories or reduce the scale of production, gradually withdrawing from the middle and low aluminum electrolytic capacitors market to focus on higher value-added, high-performance products , such as chip capacitors, industrial high-voltage capacitors and solid polymer aluminum electrolytic capacitor market. With the development of science and technology, the aluminum electrolytic capacitors from the IC, the pressure for improvement of the whole circuit, there are other capacitors in the high-voltage, high frequency, long life, small-capacity applications, the mutual penetration of pressure. Aluminum electrolytic capacitors are constantly improving, improvement and innovation. Especially with the development of science and technology, the improvement of social needs, environmental improvements, the birth of the new machine, so that miniaturization of the chip type and high-voltage large-capacity aluminum electrolytic capacitor applications are continuously expanding, growing demand big. Therefore, the aluminum electrolytic capacitors have a broad space for development and a faster growth rate. Over the past two decades, global production of electronic components began to shift to China, as one of the most important electronic components, aluminum electrolytic capacitor manufacturers are also clearly transferred to China. At present, China's aluminum electrolytic capacitor manufacturing enterprise market-based flat-panel TVs, monitors, DVDs, electronic ballasts, computers, stereos and other consumer products and industrial products. With the world's aluminum electrolytic capacitor industry is increasingly moving to China, Yada Kang electronics and a few excellent aluminum electrolytic capacitor manufacturers have mastered the high-end technology and mass production of high-end electronic ballasts, solar energy, wind power, communications and for switching power supply, inverter, automotive electronics and other aluminum electrolytic capacitors. Knowledge of electrolytic capacitors 1, the nominal parameters Is listed in the capacitor housing values. * Electrostatic capacity of the UF. Will not say more. * The operating voltage (working voltage) referred to WV, should the value of the nominal security, which means that the application circuit must not exceed this nominal voltage. * Most common temperature of 85 degrees, 105 degrees. High temperature conditions (for example, Pure Class A amplifier) ??to be preferred 105 degrees nominal. Preferably a high temperature coefficient in the general case of positive help to improve the performance of other parameters. 2, the dissipation factor, dissipation factor (DF) Sometimes the DF value of the loss angle tan. DF value is high or low temperature, capacity, voltage, frequency ... have a relationship; the same capacity, the pressure the higher the DF value is the lower. The higher the frequency DF value the higher the temperature the higher the DF value is also higher. The DF values ??are generally not marked on the capacitor or specifications introduced above. DIY selected capacitor can give priority to select the higher pressure, such as the operating voltage is 45V, the choice of 50V is not very reasonable. Although the use of 50V withstand voltage, there is nothing wrong, but the DF value considered lacking. 63V or 71V pressure will have a better performance. Of course no matter how high the price on the uneconomical. 3, the equivalent series resistance ESR ESR, high or low, the capacity of the capacitor voltage, frequency and temperature ... are related, ESR requirements as low as possible. When the rated voltage is fixed, the capacity the greater the lower the ESR. When capacity is fixed, the choice of varieties of high rated voltage can reduce the ESR. Low-frequency, high ESR, high frequency low ESR, high temperatures cause the ESR to rise. The equivalent series resistance ESR many brands can be found from the specifications. 4, the leakage current To see to understand, is the leakage! Aluminum electrolytic capacitor leakage, which is determined by the physical structure. Needless to say, the leakage current is of course the smaller the better. Higher capacity capacitor, the greater the leakage current; reduce the operating voltage to reduce leakage current. Higher pressure, in turn, selected varieties will help to reduce the leakage current. The combination of the above two parameters, the priority to select the high-pressure species under the same conditions is indeed a simple and feasible method; reduce the internal resistance, low leakage current, reduce losses and increase life expectancy. Really a lot of advantages, only price will be high. A statement, the electrolytic capacitors is much lower than the rated working voltage can not be effective enough to maintain the depolarization effect between the electrode with the electrolyte, will lead to the polarization of electrolytic capacitors to reduce ripple current, increasing large ESR, premature aging. But the premise of this argument is far less than the rated working voltage, comprehensive long-term practical experience, select the rated working voltage of the nominal value of 2/3 the normal operating voltage is more reasonable can be *. Amateur case estimate the leakage current of the electrolytic capacitors in general. Electrolytic capacitor of the same capacity in accordance with the rated withstand voltage charging, place some time after the detection capacitors at both ends of the degree of voltage drop. Down voltage, the less the leakage current is smaller. 5, the ripple current Irac Ripple current for the filter circuit for the stone is a very important parameter. Ripple current Irac as high as possible. The level of the operating frequency, the higher the frequency the Irac the greater, the lower the frequency Irac the smaller. That at low frequencies, we need to have a high ripple current, in order to get a good high-current discharge characteristics, so that the longer life of the capacitor, as well as good control driving characteristics; In fact, at high frequency ripple positive help of the wave current on the stability of the capacitor allows high frequency have a better life to extend and improve the cost-effective.
