Aluminum electrolytic capacitors, also known as aluminum electrolysis capacitors, are capacitors consisting of two aluminum foil roll electrolessly joined to two opposite edges of a porous, non-conductive material impregnated with a non-polarized electrolytic liquid, usually organic. An anode of aluminum foil is connected to one terminal of the external circuit while the other terminal is connected to an external anode, which is then connected to the external positive voltage and the anode of the capacitor. The two alternating sides of the capacitor must form an alternating current circuit.

The key feature of aluminum electrolytic capacitors is their high capacitance, which makes them useful for applications demanding high capacitance, such as high power DC circuits and power supplies. Additionally, these capacitors feature a low impedance and space efficiency. They can also be used in high-frequency circuits, audio circuits, power supplies, and data storage.

A typical aluminum electrolytic capacitor is identified by the part number, MAL210148473E3. This is a type of aluminum electrolytic capacitor designed specifically for power and noise frequency applications. The MAL210148473E3 has a capacitance value of 4.7 µF, a tolerance of ±10%, a voltage rating of 16VDC, and a temperature coefficient of -55mV/V (1 degree Celsius). The case size of the MAL210148473E3 is 7.00 x 5.00mm with a low ESR of 0.40 Ohms.

The working principle of an aluminum electrolytic capacitor is based on Faraday\'s law of electromagnetic induction. Here, the conduction of electric current in a closed circuit results in a potential difference across the two sides of the capacitor when an alternating current is applied, resulting in the potential difference between the two sides of the capacitor. The capacitance of the capacitor is determined by the number of electrons stored on the two sides or plates during the alternating current cycle. Thus, when a higher frequency is applied, more electrons are stored, resulting in greater capacitance. Additionally, the capacitance of this capacitor can be increased or decreased by adjusting the applied voltage. As a result, the MAL210148473E3 is a useful choice for high power DC circuits, power supplies, audio circuits, and other applications that require a high capacitance and a lower voltage rating.

In addition to the applications mentioned above, the MAL210148473E3 aluminum electrolytic capacitor is also ideal for high frequency, high temperature, and high power use applications. For example, it can be used for the filtering of signal and power, along with noise reduction in power supplies, motor drives, and other circuits. Furthermore, aluminum electrolytic capacitors are suitable for use in automotive and industrial applications, as well as medical devices.

The MAL210148473E3 aluminum electrolytic capacitor is an example of how mastering the technologies of electrodes, electrolytes, and other materials has allowed the production of high capacitance capacitors in a variety of sizes, voltages, and temperatures. It is also an illustration of the advantages of aluminum electrolytic capacitor technology, such as high capacitance, low impedance, and space efficiency.
