Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (AECs) are electrical component devices used for storing and releasing energy in the form of capacitance within a given circuit. They are typically composed of two metallic plates separated by an insulator, with one of the two plates made of anodized aluminum, and the other being either a metal foil or another anodized aluminum plate. AECs are highly useful components, being used in a variety of electrical applications, due to their small size and high capacitance capabilities.

MAL211814222E3

The MAL211814222E3 is a type of aluminum electrolytic capacitor developed by the manufacturer Cornell Dubilier. This particular capacitor is designed for focusing on higher capacitance values suitable for large ripple currents, and offers improved stability and reliability when compared to other AECs. It has a 380 Volt Rated Voltage and a 15mOhm impedance.

Application Field

The MAL211814222E3 is commonly used in power supply circuits and medical equipment, due to its high capacitance values, low ESR values, and long life. It is also found in other applications such as AC line filters and automotive systems. Its combination of high capacitance and low DC leakage makes it a preferred choice for many types of electrical circuitry.

Working Principle

The working principle of a MAL211814222E3 AEC is based upon the principle of electrochemistry. An electric potential is applied across the capacitor which causes an electrical current to flow, leading to the deposition of a thin oxide film on the anodized aluminum plates. This film creates the capacitance that is used in an electrical circuit.

The oxide film is highly porous, allowing ions to pass through and form an electric charge on the surface of the plates. This allows the capacitor to store energy in the form of an electric field. Electrical current is then able to pass through the device when the voltage is applied, resulting in a capacitive load in the circuit.

The MAL211814222E3 AEC has several advantages compared to other types of capacitors. First, the large size of the AEC allows it to store higher levels of energy for longer periods of time. Additionally, due to its highly porous oxide film, it has a larger capacitance than other types of capacitors, meaning that it can maintain higher-than-average voltage levels while still being able to provide a steady and reliable power delivery.

Conclusion

The MAL211814222E3 aluminum electrolytic capacitor is an invaluable component of many circuits and applications, due to its high capacitance, low ESR values, and long life. With its combination of high energy storage capacity, excellent stability and reliability, it is no wonder why this type of capacitor is a favorite among engineers and DIY enthusiasts. With its wide range of applications, from AC line filters to medical equipment, the MAL211814222E3 AEC is an excellent choice for many power supply systems.
