Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an essential component in modern electronics. They are used in a variety of applications such as controlling and storing energy, filtering signals, and providing high-frequency decoupling. In more general terms, aluminum electrolytic capacitors can be thought of as the most commonly used type of electrolytic capacitor.

The most familiar example of an aluminum electrolytic capacitor is the standard “black can” capacitor. This style of capacitor is typically hermetically sealed and contains two electrodes that are separated by an electrolyte material. The two electrodes are usually constructed from aluminum foil while the electrolyte is generally some form of aqueous solution.

Aluminum electrolytic capacitors are very sensitive to temperature changes and must be correctly designed for the application in order to ensure their long-term reliability. One such design involves replacing the aqueous electrolyte with a solid electrolyte material, such as graphite. This type of capacitor is called a solid electrolytic capacitor.

The specific type of aluminum electrolytic capacitor we will be focusing on in this article is a type known as the 381LQ152M100K012 capacitor. This type of capacitor is a high-precision device and is typically used in industrial and military applications where extremely accurate values and long-term reliability are needed. The 381LQ152M100K012 capacitor is constructed as a cylindrical aluminum case with external terminals. Inside, the two electrodes are constructed from an anode and a cathode, and they are separated by a series of layers containing an electrolyte material. The entire device is then sealed with a polymer or epoxy coating to increase the operational lifetime.

The 381LQ152M100K012 capacitor is capable of maintaining a high accuracy of up to ±2%. It is also capable of operating within an extended temperature range of -55°C to +105°C. Its rated lifetime is up to 5,000 hours at +85°C and up to 10,000 hours at +105°C. Finally, this device offers a wide range of case sizes and capacitances with values ranging from 100 µF to 10,000 µF and capacitance tolerances ranging from ±5% to ±20%.

The working principles of the 381LQ152M100K012 capacitor are quite simple. In essence, when a voltage is applied across the terminals of the capacitor, an electric field is generated which forms an electrical “bridge” between the two electrodes. This electric field allows a direct current to be stored in the electrolyte material, resulting in a capacitance that can be used to store energy and filter signals.

The 381LQ152M100K012 capacitor can be used in a variety of applications. In general, these capacitors are able to provide high-precision filtering of signal and energy storage in power supplies, circuits, and other devices. Additionally, they are well suited for use in a variety of industrial and military applications due to their long-term reliability and high accuracy.

In conclusion, the 381LQ152M100K012 aluminum electrolytic capacitor is an essential component in modern electronics. It is well suited for use in a variety of applications due to its high capacitance, long-term reliability, and wide range of case sizes and capacitances. The working principles of the device are quite simple and allow it to be used for signal filtering and energy storage.
