LNUN7152MSEGBN

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrodynamic capacitors, are widely used in electronic apparatus because they are the most cost-effective industrial grade capacitors. They are composed of two metal plates, separated by an insulating or dielectric oxide film, with a liquid electrolyte filling the gap between them. The presence of the liquid electrolyte and the large surface area of the plates give aluminum electrolytic capacitors many advantages over other types of capacitors. This makes them an ideal choice for many applications.

LNUN7152MSEGBN Application Field and Working Principle

The LNUN7152MSEGBN is a type of aluminum electrolytic capacitor that is used in various electronic applications. These components are used in the audio, video, and telecommunication industries, among others. This particular type of capacitor is designed for applications requiring high ripple current and long life. It also offers excellent load life stability.

The construction of the LNUN7152MSEGBN consists of an anode of aluminum oxide, an electrolyte of liquid or gel with a plastic outer cover. When AC voltage is applied, the capacitance of the aluminum oxide anode increases and so does the equivalent series resistance (ESR). This process is known as polarization and it limits the ripple current. The liquid electrolyte helps to reduce the ESR further because of its low viscosity.

The electrolyte also serves to reduce the temperature coefficient of capacitance, or the rate of change of capacitance. The electrolyte reduces the temperature coefficient of capacitance because it exerts a slight force on the dielectric, which is made up of an oxide film. This force increases the dielectric\'s resistance to the current as temperature increases, resulting in a decrease in the amount of current that passes through the capacitor. As a result, the capacitance remains more stable over a wide temperature range.

The aluminum electrolytic capacitor also provides excellent noise filtering. This is especially important in many electronic applications, such as audio systems. The capacitor is able to reduce or eliminate high-frequency noise, ensuring the user with excellent sound quality. Aluminum electrolytic capacitors are also reliable and long-lasting, making them an attractive choice for many applications.

In short, the LNUN7152MSEGBN aluminum electrolytic capacitors are useful components in many electronic applications, offering benefits such as improved ripple current and load life stability, reduced temperature coefficient of capacitance, and excellent noise filtering capabilities. As a result, they are an increasingly popular choice for design engineers.
