Aluminum electrolytic capacitors are a type of capacitor most commonly used in electronic circuits. EKMG251ELL220MK20S is one type of aluminum electrolytic capacitor. This capacitor has many advantages over conventional electrolytic capacitors. Because of its high reliability, long life and low ESR, it is widely used for many applications.In terms of its application field and working principle, EKMG251ELL220MK20S is an electrolytic capacitor that is used mainly for power supply circuits and filtering circuits. It works by creating a thin layer of electrolyte between two conductors, which when an electrical signal is applied, acts as a dielectric and stores the electrical charge. This capacitor has a rated voltage of 250V, capacitance of 220µF, and a maximum operating temperature of +105°C, making it suitable for power supply and filtering applications.The construction of EKMG251ELL220MK20S includes an aluminum foil anode and a loaded paper cathode, which is then immersed in an electrolytic solution. When an electrical voltage is applied between the electrodes, a thin layer of oxide forms on the anode, which prevents the charge from dissipating and allows for the capacitor to store a large amount charge. The life of this type of capacitor is determined by the thickness of the oxide layer, so it is important to ensure that the capacitance is not too high, as this could reduce the life of the capacitor. The main feature of EKMG251ELL220MK20S is its low Equivalent Series Resistance (ESR). ESR is the resistance of the capacitor’s body, which affects the capacitance and voltage rating of the capacitor. Lower ESR ratings result in higher capacitance and better performance. As a result, this capacitor has been widely used in power supply and filtering applications. In conclusion, EKMG251ELL220MK20S is an aluminum electrolytic capacitor used for power supply and filtering applications. It has a high reliability, long life and low ESR. It is constructed with an aluminum foil anode and a loaded paper cathode, which when an electrical voltage is applied, creates a thin layer of oxide on the anode that prevents the charge from dissipating, allowing it to store a large amount of charge. Due to its high reliability and low ESR, this type of capacitor is widely used in electronic circuits.
