Aluminum Electrolytic Capacitors: TC59 Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in various fields due to their high energy density and wide operating temperature range. In particular, the TC59 series of aluminum electrolytic capacitors provides a wide selection of capacitances and voltage ratings with high reliability and stability, making them an ideal choice for power supply filtering and energy storage in electronics circuits. This article will discuss the application field and working principle of TC59 aluminum electrolytic capacitors.

Application Field

Generally, TC59 aluminum electrolytic capacitors are employed in high frequency switching power supplies, switch-mode power supplies, DC/DC converters, pulse generators, and hybrid electronic circuits, as they can provide high capacitance values in a small size with a wide voltage range. They are designed with high insulation resistance and low impedance values making them capable of providing long-term stable operation in applications with wide temperature changes.In addition, the TC59 series of aluminum electrolytic capacitors is well suited for use in EMI (Electromagnetic Interference) suppression circuitry in the fields of consumer electronics and industrial automation due to its high capacitance values and low impedance levels. Moreover, these capacitors can be effectively used in high-temperature and high-voltage applications due to their robust construction and high dielectric strength.

Working Principle

The working principle of TC59 aluminum electrolytic capacitors relies on the creation of a thin oxide film on the surface of the aluminum electrodes. This thin oxide film acts as an insulating layer enabling the oxidation of aluminum ions and the formation of an electrical double layer along the surface of the electrodes. The two layers form a capacitor, and its capacitance will depend on the thickness of the oxide film.The capacitance of a TC59 aluminum electrolytic capacitor is determined by three factors: the thickness of the oxide film, the area of the aluminum electrodes, and the dielectric constant of the oxide film. The capacitance of the capacitor is inversely proportional to the thickness of the oxide film, and directly proportional to the area of the aluminum electrodes as well as the dielectric constant of the oxide film.In addition to the aforementioned capacitance parameters, the working temperature of the TC59 series aluminum electrolytic capacitors also affects the capacitance, as the temperature affects the thickness of the oxide film. When the temperature increases, the thickness of the oxide film decreases resulting in a decrease in capacitance. Conversely, when the temperature decreases, the thickness of the oxide film increases leading to an increase in capacitance.

Conclusion

In conclusion, the TC59 series of aluminum electrolytic capacitors provide high capacitance in a compact size along with wide voltage range, high insulation resistance, and low impedance. These capacitors can be used effectively in high-voltage and high-temperature applications, as well as for EMI suppression, and in power supplies and converters. The working principle of the TC59 aluminum electrolytic capacitor relies on the thin oxide film formed on the surface of the aluminum electrodes responsible for creating an electrical double layer which determines the capacitance value.
