Aluminum Electrolytic Capacitors are a type of polarized capacitor commonly used in electronics. Among them, TVA1312.1-E3 is a high voltage aluminum electrolytic capacitor with a rated voltage of 1300VDC. It is mainly applied in switching power supplies, high frequency equipment, automobiles, armed forces and aerospace equipment.

The structure of TVA1312.1-E3 can be described by two separate buildings: an anode and a cathode. The anode is the core part of the capacitor and is made of aluminum material. A dielectric oxide film is applied to the aluminum surface as an insulator, and an insulated electrolyte is added to the anode. The cathode is usually a foil with chemically treated charcoal inserted between the anode and the cathode. This arrangement creates the electric potential difference between the two ends which allows the capacitor to store energy.

The working principle of TVA1312.1-E3 is based on the difference of electric potential. When a sustained current flows through TVA1312.1-E3, negative ions flow from the anode to the cathode, while positive ions move from the cathode to the anode, creating an electric field across the dielectric oxide layer. As the electrical field builds up, electric potential energy is stored in the capacitor. This stored energy provides the ability for TVA1312.1-E3 to supply power when the main current source is interrupted due to a load change or power failure.

One of the main features of TVA1312.1-E3 is its high withstand voltage and long life. As the oxide layer thickness increases with time, the amount of leakage current decreases and the capacitance value increases. This leads to a much longer operational life compared to other types of electrolytic capacitors. The TVA1312.1-E3 is also relatively small in size and light in weight.

In addition, the TVA1312.1-E3 has good self-regulation properties. During sudden changes in applied voltage, the capacitor operates as a voltage stabilizer that prevents voltage surges and drops. This is because the dielectric layer changes its thickness automatically to adjust the capacitance value accordingly, thus maintaining the rated voltage level and protecting the load.

In summary, TVA1312.1-E3 is a high voltage aluminum electrolytic capacitor with a rated voltage of 1300VDC. It is mainly applied in switching power supplies, high frequency equipment, automobiles, armed forces and aerospace equipment, and has features such as high withstand voltage, long life, compact size and lightweight, as well as good self-regulation properties. It has a variety of application fields and the working principle is based on the difference of electric potential.
