Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a passive component that stores energy in the electrical form. It works by separating the capacitance of its two terminals which can be found in a number of electronic circuits. Since its introduction in the 1950s, it has become one of the most commonly used capacitor types. Aluminum electrolytic capacitors are typically constructed by winding two metallic foil strips around a central core of conductive material, known as the "anode". An electrolyte solution is then used to bridge the two foils and form a dielectric insulator. The capacitance of the capacitor is increased by using a thicker anode layer. This type of capacitor is suitable for applications involving frequencies up to 0.5MHz, DC bias and a relatively low temperature range.

The LLS2V821MELC aluminum electrolytic capacitor is a radial-lead, axial-electrolyte capacitor designed to store energy in a self-contained unit. It is manufactured using a robust, miniaturized construction technology for radial-leads. Its two terminals are separated using a combination of polarized and non-polarized capacitor materials. The dielectric capacitance is adjusted by a series of precisely cut layers of the anode foil. The thickness of the anode layers is varied to achieve different capacitances.

The LLS2V821MELC aluminum electrolytic capacitor is particularly well-suited for use in high-current, high-temperature applications, such as automotive and industrial motor control systems. It also has applications in low-frequency electrical power supplies and electronic circuits. The capacitance of the device can be adjusted by the number of anode layers, and is available in various capacitance levels ranging from 1µF to 2000µF.

The LLS2V821MELC aluminum electrolytic capacitor is designed to operate in a wide range of temperatures ranging from -40°C to +90°C. Its working principle is similar to that of other electrolytic capacitors, in that it stores and releases electric charge when current flows through its terminals. An electric field is created between the two terminals and the ionized electrolyte solution between them accumulates electric charge and increases the static charge across the anode layers. When the current is removed, the static charge is also removed, slowly discharging the capacitor.

The LLS2V821MELC aluminum electrolytic capacitor is manufactured in accordance with international standards, making it a reliable and cost-effective solution for a wide range of applications. It is a preferred choice for many electric and electronic systems due to its high capacitance, low leakage, long life and low cost. Additionally, it is capable of providing high voltage protection and is resistant to environmental factors such as dust, heat, temperature and humidity.
