Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as "Al-E-Caps," are passive electronic components often used in a wide variety of signal-level, power-level, and motor control applications. The design of an electrolytic capacitor utilizes a number of materials, combining the strength of one with the ductility of the other, to create a device that is both reliable and long-lasting. An electrolytic capacitor is an electrical component that uses an electrolyte to store electrical energy. In the simplest terms, an electrolyte is simply a conductive liquid (usually a type of glycol or organic material).

An LGU2A472MELC is an aluminum electrolytic capacitor manufactured by Murata and is widely used in power-level, audio, and motor control applications. It has a voltage rating of 25 volts, a capacitance rating of 470 microfarad, and a maximum current rating of 3.5 amperes at 25°C. It also features a long life of 7,000 hours at rated voltage and ambient temperature.

The main application fields of an LGU2A472MELC aluminum electrolytic capacitor are audio frequency circuits, power line filters, switching mode power supplies, power pulse circuits, microprocessors, and memory modules. Its working principle is based on the principles of electrolysis, which involves the use of an electrolyte to separate the charged particles of a substance. When a voltage is applied to the two terminals of the capacitor, the ions in the electrolyte flow in between the electrodes in the electrolytic capacitor, causing a displacement of charges between the two electrodes. This displacement of charges in turn stores electrical energy. The capacitance of the aluminum electrolytic depends on the physical size of the capacitor as well as the electrolyte used.

Another important working principle of the aluminum electrolytic capacitor is its ability to pass high-frequency current without much distortion. This is due to the fact that the electrolytic capacitor has a relatively low dielectric absorption ratio, meaning it can retain very little of the energy from the signal. This property makes aluminum electrolytic capacitors ideal for use in audio-related applications.

Overall, the LGU2A472MELC aluminum electrolytic capacitor is an ideal component for many applications due to its high capacitance, long life, and good high-frequency performance. It is used in a variety of power-level, audio, and motor control applications. The main working principle behind its functioning is the displacement of the charges in the electrolyte due to the application of a voltage. Its high dielectric absorption ratio also makes it suitable for use in audio-related applications.
