Applications of 400BXW47MEFC10X40 Aluminum Electrolytic Capacitors

A 400BXW47MEFC10X40 aluminum electrolytic capacitor is a large value electrochemical device, commonly used as a power supply filter capacitor or energy storage device. These devices are also used in electrical motors and circuit protection systems, providing capacitance values over 10,000 microfarads with working voltages ranging from 16V to 40V. Depending on the application, aluminum electrolytic capacitors are also used for AC line conditioning, depolarization, and regulation.

Working Principle of 400BXW47MEFC10X40 Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors comprise of two aluminum plates, separated by a liquid or solid electrolyte. Unlike traditional electrolytic capacitors, aluminum electrolytic capacitors are polarized, meaning that one of the plates must be positive and the other must be negative. This is why aluminum electrolytics are mainly used with DC (direct current) and not AC (alternating current).

When subjected to current flow, electrons move from the negative electrode to the positive electrode, causing an accumulation of charge on the anode, creating an electrostatic field, and creating a potential across the plates. This potential creates the required separation distance between the two plates, increasing the capacitance of the aluminum electrolytic capacitor.

The capacitance of the circuit, is determined by the size of the plates and the dielectric material between them. The thicker the plates, the larger the capacitance. The dielectric material is a liquid or solid electrolyte, which affects the capacitance value of the circuit. The higher the dielectric material\'s permittivity, the lower the voltage drop and the higher the capacitance.

Conclusion

The 400BXW47MEFC10X40 aluminum electrolytic capacitor is a large value electrochemical device, typically used as a power supply filter capacitor or energy storage device. These devices are polarized and must be used in conjunction with DC (direct current) applications. Aluminum electrolytic capacitors work by subjecting two aluminum plates to current flow, creating an electrostatic field and potential, increasing the capacitance of the circuit.
