Application Field

The MAL213827101E3 aluminum electrolytic capactiors are a kind of large capacitance aluminum capacitor and are widely used in power electronics industries. These capacitors can be used in various application fields. One of the major applications of MAL213827101E3 aluminum electrolytic capacitors is in electrical power system. These capacitors can be used to store large amount of energy which eventually helps on releasing power on-demand. They can also be used to even out the currents and voltages in power line.Another important application field of MAL213827101E3 aluminum electrolytic capacitors is medical electronics.

The MAL213827101E3 aluminum electrolytic capacitors can also be used in household air conditioning, new energy batteries for electric vehicles, and DC-DC converters.

Working Principle

An aluminum electrolytic capacitor consists of a pair of aluminum foils, one of them being an anode and another one being the sealed electrolyte-soaked paper with a cathode. The anode aluminum foil with its oxide layer is rolled and inserted into a plastic casing, the other terminal of the capacitor being the cathode-film.When the capacitor is connected to a power supply, the electric current will flow through the anode, resulting in an oxidation layer on the aluminum foil, known as the dielectric oxide layer. This dielectric oxide layer is several times thicker than the layers normally formed on common aluminum foil when exposed to air. This is because the electrolyte contains various salts and acids which are highly reactive when they\'re exposed to electric current. This dielectric oxide formed from the electrolyte has the effect of causing a voltage drop between the anode and the cathode. This voltage drop creates an electric field in the capacitor, and the energy between the electric field is stored.At the same time, the conduction between the opposite electrodes of the capacitor is made possible due to the electrolytic salt being moveable between the two electrodes. As a result of these electrical current flows in a circuit, the energy stored in the aluminum electrolytic capacitors can be released when needed, effectively increasing the capacitance of the electric circuit.

Conclusion

The MAL213827101E3 aluminum electrolytic capacitors are widely used in different types of electric circuits, such as electrical power system, medical electronics, automotive electronics, and and new energy electric vehicles. These capacitors allow for the storage of energy in an electric circuit, increasing the capacitance of the circuit and providing active power release when needed. The working principle behind the MAL213827101E3 is based on the reaction between the anode and the cathode of the capacitor with the electrolytic salt, which creates an electric field and increases the capacitance of the circuit.
