Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitors which have an anode that is made of a pure aluminum foil with an etched surface, a dielectric (made of oxide film) and a solid electrolyte. They are widely used in electronic circuits due to their ability to provide large capacitance values in a small size. The identification of an aluminum electrolytic capacitor typically includes information about the size, voltage rating and capacitance value.The 400AX4.7MEFC8X9 is an aluminum electrolytic capacitor from the MEFC product series manufactured by Rubycon. It is an axial lead, round can type aluminium electrolytic capacitor having 4.7 μF capacitance and 400V DC working voltage.

Application Field

The Rubycon 400AX4.7MEFC8X9 aluminum electrolytic capacitor is a reliable, high-performance capacitor that is used for a wide variety of applications including consumer electronics, automotive, office automation and medical equipment, computers, and communications. Specifically, its features make it ideal for use in power supplies, filters, and DC to DC converters. It can also be used in audio and video applications, consumer electronics such as DVD players, monitors and electronic switches. Additionally, its high-voltage rating makes it suitable for inverters and other devices that require voltage to be boosted. It may also be used for data-line specialty capacitors.Due to its rugged construction, the Rubycon 400AX4.7MEFC8X9 aluminum electrolytic capacitor is also suitable for use in industrial equipment, providing reliable high-performance in harsh and hazardous environments.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on its construction. When electrical energy is applied to the capacitor, positive ions (cation) of the electrolyte migrate to the anode and negative ions (anion) move to the cathode. The positively charged ions accumulate on the anode and the negatively charged ions accumulate on the cathode, forming two separate polarities that create an electric field inside the capacitor. This field in turn provides the capacitance by allowing electric charge to pass between the two sides of the capacitor. When the capacitor is discharged, the electrons return to their original position, neutralizing the charge and restoring the capacitor to its uncharged (unpolarized) state.

Durability

The 400AX4.7MEFC8X9 aluminum electrolytic capacitor is designed to provide long product life and maximum reliability, even under the toughest conditions. It is designed to withstand high levels of temperature, shock, and vibration, as well as repeated surge currents during operation.Its metalized construction and solid electrolyte provide superior temperature and voltage performance. The aluminum foil on the anode ensures low ESR and high ripple current capacity, and the special dielectric provides noncapsulation and non-catastrophic failure.Overall, the Rubycon 400AX4.7MEFC8X9 aluminum electrolytic capacitor is a reliable, high-performance device that can withstand a wide range of operating conditions, while still providing an inexpensive solution to capacitor problems across multiple industries.
