LGU2D102MELB

Aluminum electrolytic capacitors (AECs) are widely used in many electronic products due to their high capacitance and long life. The LGU2D102MELB is a popular model of aluminum electrolytic capacitor and is often used in various applications. This article will cover the application field and working principle of the LGU2D102MELB.

The LGU2D102MELB is a non-polarized, cylindrical aluminum electrolytic capacitor with a diameter of 10mm and a length of 2mm. It has a capacitance of 100µF and a rated voltage of 16V. The capacitor is rated for an operating temperature range from -55°C to +105°C. Due to its robust construction and long lifespan, the LGU2D102MELB is often used for a wide range of applications, such as automotive electronics, power supplies, and motor controls.

The LGU2D102MELB operates using electrolytic capacitance, which is a type of electrical capacitance created by the dielectric property of the electrolyte material and the electrode separator. In aluminum electrolytic capacitors, the electrolyte acts as the insulating and dielectric layer between two metal electrodes, which are typically aluminum plates that are spaced apart. The electrolyte also facilitates the formation of polarized aluminum complexes on the surfaces of the electrodes. This creates an effective capacitance between the two metal electrodes. As current passes through the capacitor, ions in the electrolyte become attracted to the polarizing field, causing the capacitance to increase. This is due to the fact that the ions form an insulating layer between the electrodes, thus enhancing the dielectric effect.

Due to these features, aluminum electrolytic capacitors are often used for applications requiring high transient current and a wide frequency range. For example, they are used in power supplies and motor drives because of their ability to absorb high voltage and current spikes. In addition, due to their large capacitance and long life, aluminum electrolytic capacitors are also used in many audio-visual devices and automotive applications. They are also used in clock circuits and frequency dividers, since they can provide a stable frequency output.

In conclusion, the LGU2D102MELB is a popular aluminum electrolytic capacitor and is often used in many applications. It operates using electrolytic capacitance, which is a type of electrical capacitance created by the dielectric property of the electrolyte material and the electrode separator. Thanks to its robust construction and long lifespan, the LGU2D102MELB is suitable for a wide range of applications, such as automotive electronics, power supplies, and motor controls.
