Aluminum Electrolytic Capacitors are among the most popular types of capacitors used in electronic applications today. They are widely used in various applications such as high frequency filtering and noise suppression, high-voltage power factor correction, and energy storage. This article will discuss the 381LQ391M400J052 application field and working principle.

The 381LQ391M400J052 capacitor is an aluminum electrolytic capacitor with a very high capacitance rating. It has a maximum operating temperature of 105°C and a capacitance range of 39.1 uF to 400 uF. This makes it ideal for a variety of applications where high reliability, high voltage, and high capacitance are required. It is also used for pulse applications and for smooth and low impedance performance.

The 381LQ391M400J052 capacitor is designed to withstand high voltage and has a long service life in the harshest environments. It is made with an anodized aluminum case and dielectric material which only allows an electrolytic solution to pass through it. This solution is electrolyzed to produce a high voltage, stable, insulated layer between two conductive surfaces.

The working principle of 381LQ391M400J052 can be explained as follows: It consists of two plates, a dielectric material, and an electrolyte. The two plates are made up of an anodized aluminum case, which is insulated from the electrolyte. The dielectric material is then placed between the two plates and is protected from electrical fields. When the capacitor is connected to a power source, current passes through the electrolyte and creates an electric field, which causes ions to move in the electrolyte and form an electrical charge.

The temperature coefficient of the 381LQ391M400J052 is low; it will maintain an almost constant capacitance across a wide temperature range. Its long life makes it appropriate for use in long-term applications. It also is ideal for applications that cover a broad range of operating temperatures and for those that need a high level of stability in the capacitor.

In summary, the 381LQ391M400J052 aluminum electrolytic capacitor is one of the most commonly used capacitors for electrical and electronic applications. It has a capacitance range of 39.1 uF to 400 uF and a high maximum operating temperature of 105°C. It is capable of withstanding high voltage and can operate in the harshest environments. It also has a low temperature coefficient and long service life. This makes the 381LQ391M400J052 an ideal choice for high frequency filtering, noise suppression, and high voltage power factor correction applications.
