Aluminum Electrolytic Capacitors are an essential component in power electronics applications, such as television, home appliances, automotive, and communication electronic products. The LGW2E561MELA35 is a type of electrolytic capacitor that is widely used in various applications and industries because of its excellent attributes. This article will discuss the application field and working principle of the LGW2E561MELA35.

Application Field

The LGW2E561MELA35 is typically used in applications that require a large capacitive load. This capacitor offers a variety of advantages, including enhanced safety, extended life expectancy, and a low ESR. The capacitor is suitable for use in switching power supplies, used in products such as televisions, computers, and communication and automotive electronics. The capacitor’s superior chemical and physical properties make it a durable choice in current-biased applications and in situations where high reliability and long life are essential.

The capacitor is also suitable for use in high-frequency circuits, such as in radio frequency circuits, as it offers excellent frequency characteristics and high stability. It can also be used in long-term storage applications because of its low leakage current. Furthermore, the capacitor is used to reduce noise due to its capacitance stiffness, and to limit switching current in power factor correction circuits.

Working Principle

The LGW2E561MELA35 is composed of an anode made of pure aluminum foil, an electrolyte such as ethylene glycol, and a cathode of oxide film. The anode and cathode plates are separated by a spacer and sandwiched between two insulated layers of plastic. When a voltage is applied between the anode and the cathode, ionic current flows from the anode to the cathode, causing the oxide film to form a dielectric between the two. This dielectric has a capacitance that increases with the applied voltage.

When the applied voltage is removed, the capacitance remains constant, but the charging current slowly dissolves the oxide film and decreases the pre-charge voltage. This is referred to as leakage current, and it is what makes aluminum electrolytic capacitors suitable for use in applications where long-term storage is required.

The LGW2E561MELA35 features a high capacitance-voltage (CV) ratio, which is essential for high power density applications, such as high power switching regulators. It also offers a low equivalent series resistance (ESR), which helps to reduce power losses due to heat. The capacitance of the capacitor is low, allowing for higher capacitance values in the application.

The LGW2E561MELA35 is also tolerant to surges of operation current, which is important in switch-mode power supplies. It also offers excellent frequency characteristics, making it suitable for use in radio frequency circuits. The capacitor has a long shelf life and is highly reliable, making it an ideal choice for long-term storage applications.

In summary, the LGW2E561MELA35 aluminum electrolytic capacitor is a versatile and reliable component that is suitable for a wide range of applications. It has an excellent CV ratio, offers low ESR values, and features good frequency characteristics, making it well-suited for high-frequency circuits. It is also tolerant to large surges and is suitable for use in long-term storage applications. This capacitor is a great choice for applications that require high performance, reliability, and long shelf life.
