Aluminum Electrolytic Capacitors, also known as Al-electrolytic capacitors, are one of the most widely used types of capacitors, and are a kind of capacitor with superior performance compared to others. These capacitors are usually made of two pieces of metal plates with dielectric aluminum oxide film in the middle, and have several advantages, such as saving space, large capacity, small volumetry, low cost, high insulation, long life, etc. They are widely used in various fields.

UBT2V220MHD8 is a kind of aluminum electrolytic capacitor. UBT2V220MHD8 refers to an aluminum electrolytic capacitor with a range of 2.2V, and an MD8 series with a rated capacitance of 35uF and 10%, which is mainly characterized by relatively large capacity and low DC leakage current. As the capacity is large, this capacitor is usually used in circuits that need to store and discharge large capacitance.

The application field of UBT2V220MHD8 is mainly in the switching power system. In the switching power supply system, capacitors need to first store energy when the voltage is turned on, and then the energy is released when the voltage is turned off. This capacitor has an advantage that it can store large capacity energy under certain parameters. Therefore, it is very suitable for use in switching power supply systems, and it is an important part in this system.

In addition to switching power supply systems, UBT2V220MHD8 also has wide application in other electronic devices. It is mainly used to reduce the ripple of the rectified circuit, as well as to smooth the voltage, filter the signal, and to provide the basis for the current in the output circuit. It can also be used as a dynamic load in pulse circuits, so that it can reduce the peak current, and delay the discharge of the pulse circuit. To sum up, UBT2V220MHD8 can be widely used for voltage stabilizing, decoupling, filtering, and energy saving.

The working principle of UBT2V220MHD8 is relatively simple. The UBT2V220MHD8 consists of layers of metal plates and an aluminum oxide film. The two metal plates are made of aluminum foil, with one side coated and one side in contact with the electrolyte. When the capacitor is connected to an electric circuit, the metal plates are charged, and a film filled with holes is formed on the surface of the metal plate. These holes are filled with ions and full of electric charges, which are used to store electrical energy in the capacitor.

Therefore, when the external voltage applied to the capacitor changes, the ions are attracted away to the new voltage, and the charge trapped inside the capacitor changes accordingly. This causes a change in the capacitance of the capacitor, and the energy stored in the capacitor also varies with the change of the capacitance. This is the principle of aluminum electrolytic capacitors.

In short, UBT2V220MHD8 is an aluminum electrolytic capacitor with a capacitance of 2.2V and a rated capacitance of 35uF. It has large capacity and low DC leakage current, and can be used in switching power supply systems as well as other electronic devices. According to the principle of electrochemistry, when the external voltage connected to the capacitor changes, the ions in the aluminum oxide film will participate in the electrical charge process, thus changing the stored energy.
