Aluminum electrolytic capacitors are energy storage components that work by storing an electric charge into an electrolyte which is usually composed of an oxide film, a separator made from paper or plastic and two aluminum sheets. These capacitors are used widely in electrical and electronic equipment due to their high storage capacity and relatively low cost. The prefix “100ZLJ120MCE10X25” denotes a series of aluminum electrolytic capacitors that are designed for use in a variety of applications.

The first two digits of the prefix “100” refer to the rated voltage in volts, which means that the capacitor can be safely operated with voltages up to 100 volts. The next two characters “ZLJ” refer to the type of dielectric material used in the capacitor, which is usually an aluminum oxide layer. The remaining two characters “120M” denote the capacitance in microfarads, with 120 microfarads being the maximum allowable value for this particular series of capacitors. The last two characters “10X25” refer to the maximum allowed operating temperature in Celsius and the maximum electrolyte leakage current at 25 milliamps.

Aluminum electrolytic capacitors can be used in a wide variety of applications. In power supplies they are often used as the main filter capacitor, helping to reduce the amount of ripple and noise present in the output voltage. They can also be used as bypass capacitors to help stabilize circuit voltages and reduce high frequency noise. They are commonly used in audio applications, such as crossover networks and decoupling circuits, and for smoothing the voltage in timing circuits and analog signal processing. Additionally, they can be used in automotive and medical electronics to help improve the overall performance of the systems.

The working principle of an aluminum electrolytic capacitor is based on the electrostatic properties of the aluminum oxide dielectric layer. When a voltage is applied across the electrodes, electrostatic charges are induced in the dielectric layer. This increases the electrical capacitance of the capacitor, allowing it to store more energy. When the capacitor is charged, the electrostatic field generated at the oxide layer causes the aluminum oxide layer to swell, resulting in a decrease in capacitance. This phenomenon is known as capacitance loss and is the main limitation of aluminum electrolytic capacitors.

In conclusion, aluminum electrolytic capacitors are widely used components due to their affordability and high storage capacity. The “100ZLJ120MCE10X25” series is designed for applications that require a capacitance of up to 120 microfarads and a voltage rating of 100 volts. These capacitors work by storing an electric charge in a dielectric layer and then using the electrostatic field generated to store energy. They are used in a variety of applications, including power supplies, audio systems, timing circuits and automotive electronics.
