LGG2Z681MELA30

Aluminum electrolytic capacitors are widely used in many applications in the electrical and electronics industry. The LGG2Z681MELA30 is an aluminum electrolytic capacitor particularly suitable for use in applications that require high surface-mountable voltage and thermal stability. It consists of two aluminum foil electrodes that are surrounded by an electrolytic wax bath. The capacitance of this electrolytic capacitor is determined by the area of the electrodes, the type of electrolyte and the effective distance between the electrodes.

The LGG2Z681MELA30 aluminum electrolytic capacitor is widely used in various applications, such as in battery power systems, switching power supplies, and power amplifiers, as well as in consumer electronics. It is also used in radio frequency (RF) transmission systems, audio and instrumentation systems, and consumer radios. Its low equivalent series resistance (ESR) makes it an ideal choice for applications with high frequency switching, high ripple current operation, and very low harmonics.

The LGG2Z681MELA30 aluminum electrolytic capacitors have a rated voltage of 6.8V and a capacitance value of 680µF. They are available in a variety of sizes and package types, such as axial and radial, and are typically mounted on printed circuit boards. They are also UL certified, meaning that they meet the safety standards set by the Underwriters Laboratories (UL).

The working principle behind the operation of the LGG2Z681MELA30 aluminum electrolytic capacitor is based on the principle of electrochemical double layer capacitance. This means that when a voltage is applied across the aluminum foil electrodes, a thin layer of electrolyte is formed on the surface of the electrode and polarized. This results in a charge separation between the two aluminum foil electrodes. This charge separation forms an electric double layer, which generates an electric field or capacitance, thus resulting in the capacitance value required by the application.

The aluminum electrolytic capacitors are also highly reliable, with a long service life of up to 10 years when used in ambient temperatures up to 40°C. The maximum operating temperature of the capacitor is 85°C. Due to the high reliability, these aluminum electrolytic capacitors are widely used in many industries, such as automotive, computer and telecommunications, consumer electronics, power supplies, instrumentation, and even medical systems.

In conclusion, the LGG2Z681MELA30 aluminum electrolytic capacitor is a versatile high-reliability capacitor that is suitable for use in a wide range of applications. Its low ESR and high stability make it an ideal solution for many applications that require high voltage and temperature stability. Its working principle is based on the principle of electrochemical double layer capacitance and its reliability is guaranteed by its UL certification.
