400BXW56MEFR12.5X30: Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in current electrical devices, such as computers, televisions, stereos, refrigerators, etc. In this article, we will discuss the application field and working principle of the 400BXW56MEFR12.5X30 aluminum electrolytic capacitor.

Application Field of the 400BXW56MEFR12.5X30

The 400BXW56MEFR12.5X30 is an electrolytic capacitor used in applications that demand superior electrical suppression. It is suited to circuits with low-frequency AC ripple currents, and its application includes power filtering, signal filtering, filtering in power supplies, and anti-interferences of pulsating signals in low-frequency systems.Due to its features, the 400BXW56MEFR12.5X30 is also used in low resistance, mobile phones, servers, laptops, and other electronic equipment. Its Operating Temperature Range is -55℃ to +125℃, and its Terminals are available with radial terminals, low-profile terminals, axial terminals, etc.

Working Principle of the 400BXW56MEFR12.5X30

The 400BXW56MEFR12.5X30 is an aluminum electrolytic capacitor, which means that it works by utilizing the electrolysis of aluminum. This involves the passage of electrical current between two electrodes that are immersed in an electrolyte solution. The electric current triggers chemical reactions that, over time, deposit a layer of aluminum oxide on the anode (the positive electrode). This layer acts as an insulation barrier between the anode and the cathode (the negative electrode), forming a capacitor. The 400BXW56MEFR12.5X30 has high capacitance due to the combination of a large surface area of the aluminum oxide layer and the high dielectric constant of the insulating electrolyte material. It also has a low equivalent series resistance (ESR) and is able to sustain a high ripple current. This makes the 400BXW56MEFR12.5X30 highly suitable for power-filtering and noise-reducing applications.

Conclusion

The 400BXW56MEFR12.5X30 aluminum electrolytic capacitor has a wide range of applications, including low-frequency AC ripple, power filtering, signal filtering, power supplies, and anti-interference of pulsating signals in low-frequency systems. Its superior electrical suppression is due to its high capacitance, low ESR, and high ripple current capabilities.
