Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that has an electrolyte, usually an organic solvent, between two aluminum foil electrodes. The two electrodes are interleaved, forming a stacked structure that increases capacitance and helps reduce losses due to self-inductance.450MXG390MEFCSN30X45 is one of the most popular aluminum electrolytic capacitors available on the market today. It has a maximum working voltage of 450V, a tolerance of +/- 5%, and a maximum tan delta of 5%. The maximum rated temperature is -55°C to +105°C. This type of capacitor is commonly used in a wide range of applications, including telecommunications, consumer electronics, and medical electronics.

Application Field

Aluminum electrolytic capacitors are most commonly used in power supplies, audio amplifiers, and other consumer electronics. Furthermore, they are used for timing and frequency generation, voltage rectification, and for storing energy and stabilizing output voltages in communication systems.In terms of consumer electronics, 450MXG390MEFCSN30X45 capacitors can be found in products such as radios, televisions, computers, tablets, and smartphones. These capacitors are also used in automotive electronics, industrial equipment, and applications such as motion control, where their low ESR and, when stacked, their low ESL, provide the necessary performance.

Working Principle

The principle of an aluminum electrolytic capacitor working is very simple. The two interleaved aluminum electrodes are separated by a dielectric layer of an organic electrolyte, which depends on the type of capacitor. A voltage is applied to the two aluminum electrodes, creating an electric field. This electric field creates a distortion in the dielectric of the electrolyte, allowing electricity to flow. This electricity flow is what provides the capacitance.The value of the capacitance of the 450MXG390MEFCSN30X45 is determined by the composition of the electrolyte, the area of the plates, and the distance between the plates. With a dielectric of a specified thickness, the capacitance is proportional to the area of the electrodes and inversely proportional to the distance between them. When a voltage is applied to the aluminum electrodes, the distortion in the dielectric will increase, increasing the capacitance even further.

Conclusion

In conclusion, the 450MXG390MEFCSN30X45 aluminum electrolytic capacitor is a type of capacitor that is widely used in a variety of applications. It is characterized by a high degree of performance and reliability, making it a popular choice for power supplies and other consumer electronics. Its working principle includes the creation of an electric field between two aluminum electrodes that is separated by a dielectric layer of an electrolyte. The value of the capacitance is determined by the composition of the electrolyte, the area of the electrodes, and the distance between them.
