Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also referred to as “electrolytic capacitors” or sometimes just “capacitors,” are components used to store electrical energy in a circuit. These components are composed of two metal plates flexibly arranged in an electrolyte solution, with the anode being the metal plate with a thicker coating and the cathode being the metal plate with a thinner coating. As electrical current passes through the cells, an electric field builds up between the plates, causing electrical charges to be stored.

One example of an aluminum electrolytic capacitor is the AHA475M2A24T-F. Capacitors such as this are constructed as a two-part unit, with the top part consisting of a casing made of aluminum and graphite composite, and a bottom part made of an aluminum case and a foil-coated in an electrolyte solution. This capacitor has a maximum working voltage of 475VDC, and a capacitance value of 2,270µF.

The AHA475M2A24T-F application field is primarily found in power systems, such as AC motor drives, power inverters, PC power supplies, UPS systems and other similar devices, which require high-frequency, high-voltage power supplies. In these type of applications, capacitors help control the electrical current, voltage, frequency, and waveform parameters, thus ensuring efficient operation of the system.

The working principle of the AHA475M2A24T-F is based on the electrostatic principle, with electricity stored or discharged from the capacitor depending on the voltage applied. With a high voltage applied to the capacitor, electrons come off the atoms in the anode and cover a thin layer of aluminum oxide, which prevents further electrons from leaving the anode. This forms an electric field and gives the capacitor its ability to store electrical energy.

The electrostatic field created by the charge stored in the capacitor, known as the capacitance, is inversely proportional to the distance between the plates. The charge stored inside a capacitor also increases when a higher voltage is applied, however, when the voltage exceeds the maximum working voltage of the capacitor the resulting high current will cause it to fail. Thus it is important to select capacitors with a maximum working voltage that is appropriate for the application.

In summary, aluminum electrolytic capacitors such as the AHA475M2A24T-F are used in a wide range of power systems for storing electrical energy. The device works by creating an electrostatic field between its plates, allowing it to store electrical charge and act as a stabilizer for a wide range of current, voltage, frequency and waveform parameters. It is however important to ensure the capacitors maximum working voltage is not exceeded in order to avoid potential damage to the device.
