Aluminum Electrolytic Capacitors- EFL-100ELL220MD05D Application Field and Working Principle

This article is about the EFL-100ELL220MD05D aluminum electrolytic capacitor, particularly its application field and its working principle. The main purpose of this article is to understand how a capacitor of this type is used and how it works. It also explains the advantages and limitations of using this type of capacitor.

Application Field

The EFL-100ELL220MD05D aluminum electrolytic capacitor is used in a variety of applications, from low frequency filtering to high frequency switching. It is a popular choice for power system filtering, such as in the power supplies of computers and home appliances. This type of capacitor is also found in telecommunications, automotive electronics and other high-reliability applications.

It can handle high working temperature and provide excellent dielectric absorption. It has high ripple current capability due to its large capacitance value. The extended operating life of the EFL-100ELL220MD05D makes it perfect for long-term applications.

Working Principle

The EFL-100ELL220MD05D aluminum electrolytic capacitor is a polarized capacitor, meaning that it has two terminals, and one is designated as the positive and one is designated as the negative. It is constructed using two plates, one made of aluminum foil and the other of a dielectric material. These plates are separated by a rolled up electrolyte, typically in the form of a gel.

When a voltage is applied to the terminals, electrons flow from the positive terminal to the negative terminal, creating an electric field that causes a polarization of the dielectric material. This polarization increases the capacitance, which is the measure of the amount of electric charge that the capacitor can store.

The advantage of using an electrolytic capacitor is that it can store much more charge than other types of capacitors. This is because its anode and cathode terminals are very close together, allowing more electric charge to be stored, which increases its capacitance.

The disadvantage of an electrolytic capacitor is that it can only handle low voltage. If too much voltage is applied, it can be damaged, so caution must be taken when using a capacitor of this type.

Conclusion

The EFL-100ELL220MD05D aluminum electrolytic capacitor is a popular choice for power system filtering, high frequency switching, and a variety of other applications. It is highly reliable and has an extended lifecycle due to its high capacitance value. It should be handled with caution, however, as too much voltage can cause damage.
