Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component consisting of two aluminum foils which are impregnated with an electrolytic solution. In most cases, these capacitors have a voltage rating (Vrmin) between one and two volts, with a leakage current of up to one milliampere. They are available in all shapes and sizes, from small flexible capacitors to large cylindrical capacitors.

400LEX3.3MEFC10X9 application field and working principle

The 400LEX3.3MEFC10X9 is an aluminum electrolytic capacitor with a rated voltage of 3.3V and a rated capacitance of 10μF. It is a type of non-polarized electrolytic capacitor, which means that the capacitance remains the same regardless of the direction of the applied voltage. It is rated for a working temperature range of -40°C to +85°C and has a maximum leakage current of 1mA.

The aluminum electrolytic capacitor is used in a wide range of applications, from motor starters, power regulators, and light dimmers to timing circuits, synchronous motors, and audio amplifiers. It can be used in AC/DC converters and power supply circuits with low voltage and high current needs. As a non-polarized electrolytic capacitor, it can also be used in AC circuits, enabling low voltage and low current requirements.

The working principle of an aluminum electrolytic capacitor is based on electrostatic laws. Basically, the aluminum plates of the capacitor are separated by a thin dielectric layer, which is an electrolytic solution. When a voltage is applied to the capacitor, a current passes through the electrolyte, creating an electric field between the plates. This electric field strengthens the capacitance of the capacitor, which is measured in Farads.

The operating voltage of an aluminum electrolytic capacitor is determined by the breakdown voltage of the dielectric layer between the two plates, but can be increased if a higher voltage rating is required. The capacitance of the 400LEX3.3MEFC10X9 can be increased by using a higher rated voltage, or a larger electrolyte dielectric layer between the plates.

The 400LEX3.3MEFC10X9 is a reliable and efficient aluminum electrolytic capacitor that can be used in a wide range of applications. It is designed for AC/DC converters and power supply circuits with low voltage and high current needs, as well as low voltage and low current requirements. With its rated voltage of 3.3V and capacitance of 10μF, it is capable of delivering reliable electrical performances in challenging environments.
