Aluminum electrolytic capacitors are widely used in almost every electronic device imaginable, from personal computers and televisions to cellular phones and radios. LGN2E391MELA30 is a type of aluminum electrolytic capacitor. This article will discuss the application fields and working principle of LGN2E391MELA30 type aluminum electrolytic capacitors.

The LGN2E391MELA30 aluminum electrolytic capacitor has a wide range of applications, including use in automotive electronics, factory automation, communications, server machines, audio and video products, and other electronic equipment. The capacitor is particularly suited for use in high voltage and high temperature environments due to its high capacitance and excellent operating temperature range. It is also suitable for use as an energy storage device due to its low ESR, ripple current capability, long working life and low leakage current, making it an ideal choice for UPS system and power supplies.

The basic working principles of a LGN2E391MELA30 aluminum electrolytic capacitors involve the movement of charge between two layers of anodized aluminum electrodes separated by a layer of electrolyte. The anodized aluminum electrodes provide a surface area for charge to accumulate, increasing the capacitance of the capacitor. The electrolyte serves to connect the two electrodes and allows for the movement of an ionic charge from one electrode to the other. The ions are attracted to the oppositely charged electrodes, resulting in the movement of electric charge and the buildup of the capacitance.

When a voltage is applied to the capacitor, the anode becomes negatively charged and the cathode becomes positively charged. This in turn causes an electric current to flow, which stores energy in the dielectric. This enables the capacitor to sustain its capacitance despite changes in the ambient temperature or applied voltage. In addition, the aluminum oxide layer provides insulation and protection against short-circuiting, which ensures that the capacitor remains safe under high voltage conditions.

The aluminum electrolytic capacitors are also ideal for use in high frequency electronic circuits due to their high frequency characteristics. The capacitor’s distributed capacitance enables it to provide a dampened voltage ripple at high frequency, allowing for improved signal quality and noise reduction. Distributed capacitance also allows for the reduction of high-frequency signal losses, enabling high-bandwidth operation.

In summary, the LGN2E391MELA30 aluminum electrolytic capacitor has a wide range of applications and working principles. It is highly suitable for use in high voltage and high temperature environments, and its low ESR, ripple current capability and low leakage current make it well suited for use in energy storage devices and UPS systems. It is also ideal for use in high frequency circuits due to its high frequency characteristics, and its distributed capacitance enables it to provide dampened voltage ripple, reducing signal losses and improving signal quality.
