Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a kind of electrochemical capacitors with a very large capacity per unit volume. This type of capacitor offers a high capacitance value for the smallest possible size, making them the perfect choice for a variety of applications. The name “aluminum electrolytic capacitor” comes from the fact that a thin layer of oxide forms on the surface of the electrolytic dielectric element, forming a stable electrolyte layer that reduces leakage current. This also makes them well suited for use in high voltage applications.

100YXG100MEFC10X23 Application Field and Working Principle

The 100YXG100MEFC10X23 capacitor is designed for general use in a wide range of applications. This aluminum electrolytic capacitor has a rated voltage range of 6.3 to 100V and a capacitance range from 10 µF to 100 µF. It has a low impedance, a long life span, and a wide temperature range of -40°C to +105°C. This type of capacitor is typically used in audio, control systems, and power supplies.

The working principle of an aluminum electrolytic capacitor is based on the dielectric oxide film of the aluminum foil. The positive surface of the electrolytic foil is coated with a thin layer of an electrolytic material. When a voltage is applied to the terminals of the capacitor, a current flows through the electrolytic material, creating an electric field that polarizes the oxide layer. The polarization reduces the dielectric constant of the oxide layer and increases the capacitance per unit area. This is why aluminum electrolytic capacitors are able to store so much more energy per unit area than conventional ceramic or paper capacitors.

The maximum operating temperature for this type of capacitor is +105°C, so it must be operated at a temperature lower than this value. Since it is an electrolytic capacitor, the maximum rated voltage should never be exceeded as this can lead to a breakdown of the dielectric layer. Similarly, any attempts to reduce the rated voltage of an electrolytic capacitor may lead to permanent damage to the capacitor.

Advantages and Disadvantages of the 100YXG100MEFC10X23

The 100YXG100MEFC10X23 capacitor offers a number of advantages, including a long life span, a low impedance, and a wide temperature range. It also has a low ESR, which allows it to respond quickly to changes, making it ideal for use in audio, control systems, and power supplies. Additionally, it is able to store more energy per unit area than conventional ceramic or paper capacitors.

While the 100YXG100MEFC10X23 capacitor offers a number of advantages, it also has some drawbacks. This type of capacitor is sensitive to high temperatures and can become damaged if the maximum rated voltage is exceeded. It also has a relatively short life span compared to other types of capacitors and is prone to higher leakage and voltage drops. Finally, aluminum electrolytic capacitors are not suitable for use in high frequency applications.
