Aluminum Electrolytic Capacitors

The 400WXA3.3MEFCT810X9 capacitor belongs to the category of aluminum electrolytic capacitors. These capacitors are constructed with two plates: a positively-charged anode and a negatively-charged cathode. These plates are surrounded by a dielectric sheet and filled with an electrolytic material.

Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in devices such as power supplies, consumer electronics, computers, circuit boards, and electronic tools. The 400WXA3.3MEFCT810X9 capacitor is designed for use in applications that require a low-loss dielectric that can handle a large voltage ripple. The capacitor consists of two electrodes separated by an anode foil, an electrolyte, and a dielectric oxide film. The dielectric oxide film is composed of aluminum oxide, which has a high dielectric constant and low leakage current. This allows the capacitor to store more electric charge per unit of volume than conventional capacitors.

The working principle of the 400WXA3.3MEFCT810X9 capacitor is based on the change of capacitance as a result of applied voltage. When a voltage is applied to the capacitor, a current flows through the electrolyte, ionizing the electrolyte and forming an electric double layer at the center of the capacitor. This double layer provides the capacitance, which is then stored on the dielectric oxide layer. The voltage across the capacitor is then determined by the capacitance and the applied voltage, and the charge stored is proportional to the applied voltage.

The 400WXA3.3MEFCT810X9 capacitor has a low loss and low leakage current characteristics, making it ideal for applications such as surge protection and high voltage DC-DC converters. It is also capable of withstanding high temperature up to +105°C, making it ideal for use in harsh environments. Furthermore, it has a long service life and is capable of withstanding high vibration and shock, making it highly reliable.

Advantages of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have several advantages, such as low cost, high capacitance, low ESR (equivalent series resistance) and long life. The low cost of the 400WXA3.3MEFCT810X9 capacitor, in particular, makes it attractive for applications in which cost is a concern. Additionally, the long lifetime of the capacitor means that it can be used in applications that require long-term reliability, while its low ESR can help reduce design costs and improve efficiency.

Finally, the 400WXA3.3MEFCT810X9 capacitor is highly versatile, capable of being used in a wide range of applications. Its low cost, long life, and low ESR make it suitable for use in consumer electronics, telecommunications, industrial, medical, and automotive applications.

Conclusion

The 400WXA3.3MEFCT810X9 capacitor is a type of aluminum electrolytic capacitor. It is an ideal low cost option for various applications that require a low-loss dielectric that can withstand high voltage. Its capabilities include a long life, low ESR, high capacitance, and high vibration and shock resistance.
