Aluminum electrolytic capacitors are widely used in electronic circuits, and the B41231D6478M000 is one of the most popular products on the market. The primary application fields for this type of capacitor range form power supply filters, intermediate frequency circuits and in communication equipments. Its working principle is based on the physical phenomena of electrolysis and the metal oxide characteristic.This capacitor is made up of an anode, which is an aluminum foil and etched with a large number of fine meridian lines, a paper dielectric which is coated with an organic film, a thick electrolyte soaked in cellulose, and a cathode of electrolytic paper. Under the certain voltage, there is an ion exchange between the electrolyte and the anode. A large number of positive ions are deposited onto the anode\'s meridian surface and form a conductive layer, which eventually closes the oxide film on the aluminum foil surface, thus forming a parasitic capacitor on the anode surface. The capacity of the aluminum electrolyte capacitor is determined by the volume of the electrolyte, and it is influenced by the voltage and temperature. It is also characterized by its high frequency performance, which is especially important for communication applications. Since an aluminum electrolytic capacitor is an electrolyte chemical device, it has the characteristic of being able to increase in capacitance value with working temperature. So its temperature coefficient is generally certain, about +25% to +85%, depending on the type. In addition, aluminum electrolytic capacitors also have a low dissipation factor, and they are very reliable with long life expectancy, even after thousands of hours of use. Due to the use of special techniques such as calcium hydroxide electrolyte, special boron-aluminum oxide film and a number of other technologies, capacitors of this type are highly resistant to shock, vibration and impact. To sum up, the B41231D6478M000 aluminum electrolytic capacitor is the perfect product for a wide range of electronic products, from simple power lines, communication circuits, intermediate frequency circuits, and many others. Its superior performance and reliability makes it the electronic product of choice for many industry applications.
