Aluminum Electrolytic Capacitors - EMLF160ADA471MJA0G Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are characterized by relatively large capacitance and relatively small volume. They are widely used in various applications, including EMLF160ADA471MJA0G.

EMLF160ADA471MJA0G aluminum electrolytic capacitors are non-polar capacitors that are designed for high voltage power supply circuits. They consist of an anode aluminum foil and an electrolyte soaked paper separator. The two are wound together and then inserted into a cylindrical aluminum shell. The capacitor can be connected in parallel or series depending on the application.

These aluminum electrolytic capacitors have a small capacitance value range of 47 to 100 μF and a capacitance tolerance of ±20%. They are available in two different dielectric versions: X5R and Z5U. The capacitance value and dielectric type are marked on the unit for easy identification. The dissipation factor rating is 0.21 at 25°C.

EMLF160ADA471MJA0G capacitors can be used in a wide range of applications such as power supplies, amplifiers, motors, transformers, and air conditioners. They are used in a variety of industries including automotive, telecommunications, medical, consumer electronics, and aerospace. These capacitors are highly reliable and have a long service life, making them an excellent choice for most projects.

Working Principle of Aluminum Electrolytic Capacitors

The main component of an electrolytic capacitor is an aluminum foil strip that is rolled in a spiral fashion, separated by a paper separator soaked in electrolyte. When electrical energy is applied to the aluminum foil, a thin layer of highly conductive oxide forms on its surface. This layer acts as a dielectric between the anode and the cathode. This is the main reason why aluminum electrolytic capacitors can offer such large capacitance values in a small form factor.

When AC voltage is applied to the capacitor, the AC current will flow through both the anode and the cathode and is absorbed by the dielectric layer. This current is also responsible for the charging and discharging of the capacitor. The charge stored in the capacitor is proportional to the product of the voltage applied to the capacitor and the time it is applied. As the voltage of the AC energy source increases, the amount of stored charge also increases.

When the voltage is removed, the capacitor dischargesenergy stored in the form of electrical charges. This process is usually expressed using an equation, which states that the voltage drop across the capacitor is proportional to the time constant of the capacitor and the rate of change in current.

Aluminum electrolytic capacitors are very reliable and robust, and can handle extremely high temperatures. They are also relatively inexpensive, which makes them a cost-effective solution for most applications. However, they should be handled with care as they can easily be damaged if the wrong type of voltage is applied.

Conclusion

EMLF160ADA471MJA0G aluminum electrolytic capacitors are ideal for a variety of applications. They offer high capacitance, a wide capacitance tolerance, and a low dissipation factor. The working principle of aluminum electrolytic capacitors is based on the formation of a thin oxide layer on the aluminum foil that acts as a dielectric between the anode and the cathode. These capacitors are highly reliable and have a long service life, making them an excellent choice for most projects.
