Aluminum Electrolytic Capacitors

EMZA800ADA470MJA0G is a type of aluminum electrolytic capacitor. Here, we will discuss its application field and working principle.

The Application Field

Aluminum electrolytic capacitors are widely used as energy storage devices in fields such as power, communications, instrumentation and automotive electronics. EMZA800ADA470MJA0G is a popular product in communications. Its application in the telecommunications industry can be divided into two main categories, namely data transmission and signal reception and processing.

• Data transmission applications can include power amplification in antennas, ESD protection for the communications interface and surge protection for high-frequency signal transmission.
• For signal reception and processing, it is widely used for common-mode and differential-mode noise elimination, which improve the signal-to-noise ratio, as well as isolating power-imbalanced circuits.

The Working Principle

The working principle of aluminum electrolytic capacitors is similar to that of an electrolytic cell. There is a thin oxide layer formed on aluminum on the inner plate of the capacitor. On one end of this oxide layer, there is a liquid electrolyte, which acts as a separator between the electrodes. This design allows the capacitor to obtain a larger capacitance than a planar capacitor.

When a voltage is applied to the capacitor, the electrons from one side of the device move through the oxide layer, crossed the electrolyte barrier and finally reach the other side and cause an electric current. This will continue as long as an electric field is present, until the capacitor reaches electric equilibrium. At this point, the electric charges on the two plates are balanced and the current stops flowing.

Conclusion

To conclude, EMZA800ADA470MJA0G is a type of aluminum electrolytic capacitor and is used in applications such as data transmission, signal reception and processing and noise elimination. It works on the principle of an electrolytic cell, where the charge is balanced out by the electron flow across the oxide layer and through electrolyte fluid.
