Aluminum electrolytic capacitors are the most commonly used capacitors in power electronic applications, and TVA1148 is an advanced electrolytic capacitor developed by TDK-EPC. The TVA1148 aluminum electrolytic capacitor has a wide range of applications, such as filtering, signal processing, switching and so on, and is especially suitable for high power and high frequency applications.

The TVA1148 aluminum electrolytic capacitor is characterized by its dielectric material, which is composed of aluminum foil and an organic film. The organic film on the surface of the aluminum foil is made of a special inorganic material, which has the function of waterproof and anti-explosion. In addition, the TVA1148 capacitor has a special construction design, which can reduce the loss of the internal heat dissipation, and the self-healing function allows the capacitor to automatically restore after abnormality.

The working principle of the TVA1148 aluminum electrolytic capacitor is based on the principle of capacitance. The capacitor is filled with liquid electrolyte in the sealed aluminum shell, which plays the role of electrolyte. The positive pole is connected to the anode of the aluminum foil, and the negative pole is connected to the carbon sheet specially added in the electrolyte, and each pole of the capacitor generates an electric field, so that a certain capacitance can be realized.

Under the effect of the electric field, the electric field will cause the ions in the electrolyte to move, and the positively charged ions will be attracted to the negatively charged carbon sheet, while the negatively charged ions will be attracted to the positively charged aluminum foil. At the same time, due to the change of the ions, the electric characteristics of the capacitor are constantly changing, so the capacitance of the capacitor can continue to increase.

In addition, due to the special design of the TVA1148 aluminum electrolytic capacitor, it has the characteristics of high rate of capacitance, low resistance, low loss and high frequency response. This makes the TVA1148 capacitor an ideal choice for power electronics applications where high frequency, high power, high reliability and high drawing force are required.

In conclusion, the TVA1148 aluminum electrolytic capacitor has many advantages and is widely used in applications such as filtering, signal processing, switching and so on. It is characterized by its dielectric material, which is composed of aluminum foil and an organic film, and its special construction design, which can reduce the internal heat dissipation losses, and its self-healing function which can restore itself after abnormality. In addition, the TVA1148 capacitor also has high rate of capacitance, low resistance, low loss and high frequency response, making it an ideal choice for high power applications.
