Aluminum electrolytic capacitors are an important section of passive electronic components, which are widely used in many fields of our daily life. They are made of an aluminum roll with a very thin oxide film layer as an electrolytic medium. UMJ1E220MDL aluminum electrolytic capacitor is a hybrid aluminum electrolytic capacitor with a metal layer, which has the characteristics of high capacitance, high voltage, and long operating life. Generally speaking, the application fields and working principles of this aluminum electrolytic capacitor are explained as follows.

Application field

UMJ1E220MDL aluminum electrolytic capacitors are mainly used in signal processing circuits, including power amplifiers, digital TV (DTV), and audio systems. It can be used in many kinds of circuits to filter some low frequency or high frequency signals, improve the performance of the circuit, and protect the power supply from damage.

Working principle

The working principle of UMJ1E220MDL aluminum electrolytic capacitor is made up of basic principles such as capacitive reactance, electrolyte capacitance, dielectric absorption, current leakage, and polarization, which work together to store energy. Firstly, two parallel metal plates constituted an electrolytic capacitor, which can effectively store electrical charge. Secondly, the dielectric layer formed from an electrolyte, which can separate the positive and negative plate in the capacitor. Thirdly, the metal layer acts as a conductor, allowing the electrons to easily flow through the capacitor. Finally, the current leakage through the oxide film layer is reduced, ensuring the capacitor’s stable operation.

In conclusion, UMJ1E220MDL aluminum electrolytic capacitors are widely used in many fields, mainly for signal processing, and they can be used in power amplifiers, digital television and audio systems. Their working principle is based on the capacitance, dielectric absorption, and current leakage. Moreover, the metal layer allows for easy electron flow through the capacitor, and the oxide film layer reduces current leakage and ensures stable operation.
