How to find the long life of aluminium electrolytic capacitor?
aluminum capacitor is usually used when the compact design, but this kind of capacitor is known as the big loss capacitor, how to find the long life of aluminum electrolytic capacitor? Purchase long working life of aluminum electrolytic capacitor is not easy, because different manufacturers specification table format each have differences, every company wants the best performance of the product in the most when the eye position, to highlight their products excellent, make to put all kinds of products in the same online more twists and turns. Like other capacitors, aluminum electrolytic capacitor must clearly indicate its voltage and capacitance value, generally speaking the higher the value, the better the products. In addition usually need a smaller size and the equivalent series resistance ( ESR) , this will cause a higher cost. The four factors are often interrelated. These Numbers can usually be found in the specification, but once join the long life consideration, it is complicated, because the working life of the capacitor is related to working temperature: a manufacturer may refers to the + 85? C working temperature can achieve certain working hours, while the other manufacturer's working life may be based on + 105? C working temperature. It is obvious that the starting point is to find out the requirements of the device working hours, and then check their work environment conditions. Normally, in low temperature will prolong the working life, if the temperature of the working environment there will be no higher, select a lower working temperature and long life device will be a right decision. Our price is also an important factor, but it will take and breakdown cost consideration together. Such as the need to long working life of capacitor is one of the reasons about equipment will be installed to the difficult such as offshore oil Wells, and so on the location of the contact, so, capacitor price compared with capacitor failure need huge maintenance costs is insignificant. Designers also need to find the specific meaning of the end of the working life. After a lot of components aging performance decline, but they are still working parameters in an acceptable range. An application can accept parameters, however, does not necessarily apply to another application. Power applications, for example, when the capacitor is used as the input buffer, life end means that when the output voltage is too low, capacitance will decline to below enough for DC - DC converter provides energy levels. In the output buffer application, life end represents the impedance rise, beyond the intersection of output voltage and ripple voltage, makes the power drive circuit problems. Electrolytic capacitor is the most common reason for failure is the evaporation of electrolyte itself with time, make the electric property changes. Capacitor is made up of two intermediate in conductive layer of a layer of dielectric separator, the anode is a piece of the expanded surface area of aluminum, and the oxide layer is used as a dielectric layer above. Work is a conductive liquid electrolyte, and thus have the problem of evaporation. Is the second piece of aluminum cathode, electrolyte used in the current to work. Anodic oxidation is used to extend the life of the capacitor manufacturing process, to ensure that the use of the material with high purity.
