Aluminum Electrolytic Capacitors are widely used in today’s electronic industry because of their excellent properties. UPJ2A220MPD is a type of aluminum electrolytic capacitor which is characterized by small size, high capacity and long life.

UPJ2A220MPD has a wide range of application fields. It is mainly used in notebook computers, LED TV energy saving system, LED driver power supply, wireless power supply and other power control circuits. For example, in a notebook computer, it can be used to store and release energy that is used for data processing or other tasks when power is limited. In an LED TV energy saving system, the UPJ2A220MPD can be used to reduce the impact of power surges that come from the switching power supply rectifier output voltage. In addition, it can also be used in cooling fan control, medical equipment, etc.

The UPJ2A220MPD aluminum electrolytic capacitor consists of three main working parts. The anode, which consists of aluminum foil with oxide layer on its surface and a roll of electrolytic paper soaked in solution. The cathode is the anodized layer of aluminum oxide, which is the main oxide that forms the dielectric. The electrolyte is usually composed of an aqueous solution of an alkali metal halide, such as sodium chloride or potassium chloride. The cathode and electrolyte forms the capacitance of the capacitor, which is used to store electrical energy.

The working principle of the UPJ2A220MPD aluminum electrolytic capacitor is relatively simple. When a voltage is applied across it, a current will begin to flow through the electrolyte and the cathode, supplying the capacitor with a charge. As the charge accumulates on the electrodes, a dielectric will form between the anode and the cathode, which will reduce the current flowing through the electrolyte and the cathode and thus reduce the capacitor\'s capacitance. The amount of charge that is stored depends on the voltage as well as the capacitance of the capacitor.

The UPJ2A220MPD aluminum electrolytic capacitor is an excellent choice for a variety of applications because of its excellent properties such as high capacity, long life, small size, and low leakage current. It is also reliable, as it is able to withstand high voltages and temperatures, as well as high vibration levels.
