Aluminium Electrolytic Capacitors

Aluminium electrolytic capacitors (AECs) are capacitors that have an electrolyte (usually liquid) and two metal plates usually made of aluminium. These capacitors work on the same principle as a battery and possess a large capacitance value for a small volume and are relatively cheap to produce making them ideal for a variety of applications. The MAL229957152E3 is a type of radial cylindrical AEC made up of an aluminium shell, a spacer, a separator and two screws for connection.

MAL229957152E3 Application Fields

Since AECs possess such a high capacitance value, they can be used in a variety of different applications. The MAL229957152E3 capacitor, due to its relatively large capacitance value, is ideal for use in power supply filtering and ripple current elimination applications, such as in AC-DC switching power supplies and DC to DC converters. It can also be used to store electrical energy or engage in timing circuits and applications due to its ability to quickly charge and discharge.

MAL229957152E3 Working Principle

The working principle of the MAL229957152E3 is the same as for any AEC. When an AC voltage is applied to the capacitor leads, the electrolyte, which acts an insulator, forms a barrier that prevents the flow of electrons and charges up the capacitor. Unlike other types of capacitors, AECs have a much higher capacitance value for a given volume due to their unique construction. The charge stored in the capacitor is then used to supply the required current during discharge as the same barrier that was preventing electrons from flowing during charge is now broken, allowing current to flow freely.

Conclusion

The MAL229957152E3 is a type of radial cylindrical aluminium electrolytic capacitor that is especially suited for power supply filtering and ripple current elimination applications due to its relatively high capacitance value. To achieve this, the capacitor is constructed from a combination of an aluminium shell, a spacer, a separator and two screws for connection and works on the same principle as a battery - it stores electrical energy during the charging phase and releases it during the discharge phase.
