Aluminum Electrolytic Capacitors

Electrolytic capacitors are divided into two main types: aluminum electrolytic capacitors and tantalum electrolytic capacitors. Aluminum electrolytic capacitors have higher volumetric efficiency, but their reliability and life are poorer than tantalum electrolytic capacitors. The EKZN500ELL471MK20S belongs to the aluminum electrolytic capacitor family. It is of axial type and it has a small size. It is mainly used for signal filtering and de-coupling in power sources, battery charging and current-limiting circuits.The EKZN500ELL471MK20S is made up of an aluminum foil element, an electrolyte, and a paper separator. The element consists of two aluminum foil sheets, one of which is made of electrolytically treated aluminum in order to form the anode foil and the other is made of regular aluminum which forms the cathode. The electrolyte is usually a high viscosity liquid that serves to fill the gap between the foils and it is also the medium through which current passes in the capacitor. The separator or dielectric is typically made of a paper material that seals the capacitor and prevents leakage of the electrolyte.The working principle of the EKZN500ELL471MK20S is based on Faraday’s law of electrochemical equivalent. It states that when an electric current is passed through an electrolyte, the electrolyte must undergo a proportional amount of electrochemical transformation which is determined by the amount of current that passes through it. In other words, the electrolyte acts as a conductor, allowing the electric current to pass through it in the form of an electron flow. As a result, the aluminum anode of the capacitor is oxidized, while the cathode gets reduced and this process generates a potential difference between the electrodes. This potential difference or voltage across the capacitor serves as a charge store and accordingly, the capacitor can store and discharge current.The EKZN500ELL471MK20S capacitor also has a particular working environment that must be adhered to for it to function properly. Its working temperature range is -40°C to +85°C, and its working humidity range is -40°C to +105°C. In addition to this, it must be placed in the vertical direction and given enough allowance for air circulation. These conditions must be met in order for the EKZN500ELL471MK20S capacitor to deliver its rated capacity within the specified working environment.The EKZN500ELL471MK20S capacitor is particularly suitable for use in power supplies and current-limiting circuits. This is because it has the ability to rapidly discharge the stored energy, thereby avoiding potential overvoltage damage in the circuit. Furthermore, its small size is beneficial for the design and overall performance of the end product, since it can be integrated into the circuit with minimal space requirements. In conclusion, the EKZN500ELL471MK20S capacitor is a type of aluminum electrolytic capacitor that is mainly used in power supplies, battery charging and current-limiting circuits. It is designed to be resistant to voltage spikes, and because of its small size it can be integrated into circuits with minimal space requirements. Finally, it must be brought into a suitable working environment for it to deliver its specified capacity.
