Aluminum Electrolytic Capacitors play a crucial role in today’s electronics and communications systems. The LGN2G221MELA35, a surface mount aluminum electrolytic capacitor, is designed to provide reliable and efficient operation in a variety of applications. Its rated voltage, which ranges from 6.3 VDC to 200 VDC, makes it suitable for a wide range of electronic applications, including those in telecommunications, instrumentation, and DC power supplies. In this article, we’ll take a closer look at the LGN2G221MELA35, discussing its application field and working principle.

The LGN2G221MELA35 is capable of handling currents from 1.0A to 10A, and can produce capacitance values from 22μF to 180μF. It is designed for operating temperatures between -40°C and +105°C, making it suitable for automotive, military, medical, and other applications with extreme temperature requirements. Additionally, its small size makes it quite attractive when it comes to applications with space constraints. The LGN2G221MELA35 is also highly reliable and durable, making it a favorite among engineers who rely on reliability in their design.

The LGN2G221MELA35 is designed to create a capacitive element of a specific capacitance value. This element is made of two aluminum sheets and two surfaces of separator film, which are impregnated with a liquid electrolyte. One of the aluminum sheets is rigid, while the other is flexible. When the capacitor is subjected to a voltage, an electric field is applied, creating a potential difference and a polarization effect between the aluminum sheets. This polarization causes a temporary leakage of charge, which is balanced by the in-flow of electron charges from the electrolyte and the out-flow of cations from the aluminum sheets, forming an electric double layer at the interface.

The electric double layer creates an opposing electric field, which is proportional to the applied voltage. This electric field is responsible for regulating the flow of current through the capacitor. The capacitance value of the LGN2G221MELA35 is determined by the electrical parameters, such as the permittivity and surface area of the separator. These parameters can be varied to produce different capacitance values.

As a surface mount aluminum electrolytic capacitor, the LGN2G221MELA35 is well suited to applications that require a finite amount of energy storage, such as filtering, voltage stabilization, and motor startup. It is also commonly used in power supply circuits, where it serves as a buffer for a stable voltage. Additionally, the capacitor’s ability to heat up quickly and dissipate the heat makes it a valuable tool for protecting circuits from overcurrent situations.

In terms of output characteristics, the LGN2G221MELA35 has a high stability of capacitance over temperature. Its high ripple current rating also ensures that it is capable of handling large transient currents with minimal noise. Its relatively low ESR (Equivalent Series Resistance) makes it well suited for low ESR circuits, such as switching power supplies and audio applications.

In summary, the LGN2G221MELA35 is an efficient and reliable aluminum electrolytic capacitor. Its small footprint and high voltage ratings make it suitable for a wide range of applications. Additionally, its high current and ripple current ratings ensure its capability to handle high transient currents. Its low ESR makes it ideal for low ESR circuits. Its robust construction and efficient operation make it an excellent choice for a variety of electronic applications.
