Introduction

Aluminum Electrolytic Capacitors, also known as electrolytic capacitors, use aluminum foil as an anode and an etchant oxide film as a dielectric. The negative electrode of the capacitor is a liquid electrolyte, and the charging voltage must have a certain polar direction. This type of capacitor has stable capacitance, high efficiency, large capacity, long service life, good humic performance, and stable frequency characteristics. It is widely used in various occasions. AVGA337M25G24T-F is one of the aluminum electrolytic capacitors.

AVGA337M25G24T-F application field and working principle

Application Field

AVGA337M25G24T-F is suitable for use in power electronics, telecommunications, instrumentation, computers, and other electronic circuit, and it has good heat resistance. It is necessary to add a cold source for heat dissipation when working in a high temperature environment, so as to ensure the normal operation of the capacitor. Also, with its quick charge and discharge characteristics, it can be used in circle resonance circuits, and generally can reach its rated value in 0.5 seconds. This type of capacitor is also suitable for occasions with high requirements, such as strong direct current, alternating current, high reliability, large capacity, and vibration resistance applications. Specifically, it is suitable for computer auxiliary power control, regulator, signal transfer, audio filter, motor starting, overshoot absorption, frequency division, time constant, phase shift, ripple filter, de coupling circuits etc.

Working Principle

Ceramic capacitors are commonly used because of their low cost and comparative simplicity in construction. However, electrolytic capacitors are more electronically complex and higher cost, but offers several advantages over ceramic capacitors including higher ratings and higher capacitance.The working principle of AVGA337M25G24T-F is that its two poles are connected to the circuit to be charged, and the other two poles are connected to the charged electric energy source. Then, when the current flows from the positive pole of the power supply to the electrolyzer, the positive pole of the capacitor will be charged, and the negative pole is connected to the electrolyte. At the same time, negative ions in the electrolyte are attracted to the negative pole of the power supply, and positive ions are attracted to the positive electrode of the capacitor. In this way, a large amount of electricity can be quickly accumulated in the capacitor, and then stored in the capacitor, supplying power for other electronic devices that need electricity in the circuit.At the same time, the aluminum foil is coated with a layer of oxide film as the dielectric, which is the necessary condition for the capacitor to work effectively. In addition, the liquid electrolyte can also increase the surface area contact between positive and negative electrodes, so that more ions can be carried, resulting in higher capacitance.

Conclusion

To sum up, aluminum electrolytic capacitors, such as AVGA337M25G24T-F, are an important part of electronic circuits. They have the advantages of high efficiency, large capacity, long service life and good humic performance. They are widely used in various occasions in power electronics, telecommunications, instrumentation, computers and other electronic devices. When working, it needs two poles connected to the circuit that needs charging and the other two connected to the power source. Its excellent properties are achieved by using aluminum foil as an anode and an etch oxide film as a dielectric, as well as liquid electrolyte to increase the surface area of contact between the positive electrode and the negative electrode, thus increasing its capacitance.
