Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often referred to as "electrolytic capacitors" or simply "electrolytics", are one of the most widely used capacitors in electronics and electrical fields. They are an essential component of many electrical circuits and are used to store and discharge charge, as well as provide more energy to the circuit. The type of capacitor referred to in this article is the LGY1V123MELA50 aluminum electrolytic capacitor.

Capacitance and Voltage Rating

The LGY1V123MELA50 aluminum electrolytic capacitor offers a capacitance value of 1.2μF and a voltage rating of 50V. Its capacitance value determines its ability to store charge and its voltage rating determines how much voltage the capacitor can withstand, how much current it can handle, and how much energy it can store.

Construction of the LGY1V123MELA50

The LGY1V123MELA50 aluminum electrolytic capacitor is a polarized capacitor, meaning it has positive and negative terminals. Inside the capacitor are two aluminum foil strips separated by a dielectric paper separator. The one side of the foil strips are further coated with a liquid electrolyte, usually made of ethylene glycol mixed with water, which functions as the charge collector. The other side of the strips are brushed with a graphite paste to prevent the electrolyte from flowing through the metal strips. The metal strips and the dielectric paper separator act as the two plates of a capacitor, while the electrolyte serves as a medium through which charge can pass.

Working Principle

The working principle of the LGY1V123MELA50 aluminum electrolytic capacitor is based on the basic construction of a polarized capacitor. When a voltage is applied across the terminals of the capacitor, electrons are drawn to the aluminum foil strips with the electrolyte. This causes the electrolyte to form ions, which then causes electric current to flow through the capacitor. This flow of current creates an electric field that builds up between its two plates. This field stores the charge and develops an electric potential. When the voltage across the capacitor is reduced or removed, the electric field slowly dissipates, releasing the charge it was storing.

Application Fields

The LGY1V123MELA50 aluminum electrolytic capacitor is typically used in pulsed circuits, such as power supplies, audio amplifiers, motors, and other applications that require large amounts of energy to be stored and released quickly. The vast majority of these capacitors are also used in decoupling circuits, providing an efficient and cost-effective way to protect sensitive electronic components from voltage transients that can occur during power up or power down. Additionally, due to their high power and energy storage capabilities, the LGY1V123MELA50 aluminum electrolytic capacitors are commonly used in the construction of lighting and electric motors.
