Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor (ALEC) is a type of capacitor that uses an aluminum oxide film as a dielectric material. It is primarily composed of two aluminum foils, each coated with an electrically conductive material. The electrodes are separated by an electrolyte, usually an organic solvent, such as an alcohol, or a gel. ALEC can be classified as non-polar, polar, double layer, and surface mount. The E81D630VNN472MR35T is specifically an aluminum electrolytic capacitor which belongs to the Polar series of capacitors. This type of capacitor has one two-sided anode and cathode which serves as displacement electrodes immersed in an electrolyte. The electrolyte prevents the two electrodes from coming in direct contact. The standard operating temperature range of E81D630VNN472MR35T is -40C to +85C. The capacitance of this series is from 0.1μF to 2700μF with the rated working voltage of 4V-450V. The primary application of the E81D630VNN472MR35T is for general-purpose filtering, decoupling and bypassing applications, energy storage, power line filtering and noise suppression. It is primarily used in audio-video and industrial control circuits, computer power units, home appliances, DC-DC converters, automotive circuits, and other electronic circuits requiring high-ripple current ratings.The basic working principle of the aluminum electrolytic capacitor is the same as that of any other standard capacitor. When the capacitor is connected with a DC voltage source, electrons from the negative terminal of the DC source flow towards the negative electrode of the capacitor, thus establishing a field. These electrons are attracted by the anode creating a charge at the anode. This phenomenon also causes a displacement current between the anode and the cathode which results in the establishment of a dielectric field in the electrolyte medium. This dielectric field produces a polarization effect, which in turn develops a cavity between the anode and the cathode. The capacitance of the E81D630VNN472MR35T is determined by the area of the electrodes, the distance between them, the dielectric Constant “K” of the electrolyte medium, the thickness of the dielectric medium and other minor factors. The E81D630VNN472MR35T has a very high capacitance and maintains a very steady load even when subject to a wide range of operating temperatures. It is also very reliable over a long period of use.From its primary application to the working principle, the E81D630VNN472MR35T stands as a versatile and reliable aluminum electrolytic capacitor that offers a wide range of functionality. It is widely used in a variety of industries and applications making it a popular choice among electronic design engineers who rely on the stellar performance and long lasting reliability.
