Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are a type of capacitors that use electrical double-layer capacitance and chemical surface reduction. They are generally composed of a aluminum oxide film, a solid electrolyte, electrodes, and structural dielectric components. AECs are used in a variety of electronic applications, from automotive electronics to telecommunications hardware and cell phones.

What is 400LLE2R2MEFC8X9?

400LLE2R2MEFC8X9 is a type of aluminum electrolytic capacitor. It is classified as a radial leaded aluminum electrolytic capacitor and is used in various applications including cell phones and computer motherboards. It is rated for 2.2uF at 16V and is designed to measure 8mm in diameter.

Application Field and Working Principle of 400LLE2R2MEFC8X9

400LLE2R2MEFC8X9 is typically used in digital signal processing (DSP) circuits, AC/DC power supply circuits, switching power supplies and microprocessor-based input/output (I/O) circuits. It is used to store small amounts of electrical energy and when the voltage is applied, it is able to effectively bypass the flow of current.The device consists of two aluminum foils which act as the anode and cathode of an electrolytic cell. The anode is coated with a thick layer of aluminum oxide which functions as the dielectric and separates the two foils. When a voltage is applied across the capacitor, an electric field forms between the two foils and causes electrons to move from the anode to the cathode, causing the aluminum oxide layer to reduce in thickness. This produces an electric conduction path between the two foils and increases the capacitance of the capacitor.The combination of electrical double-layer capacitance and chemical surface reduction in a 400LLE2R2MEFC8X9 aluminum electrolytic capacitor makes it a very efficient and compact means of storing electrical energy. It is highly reliable and is able to withstand high levels of shock, vibration and temperature change. In addition, the capacitor has a lifespan of several thousand hours, making it a great choice for digital signal processing and AC/DC power supply circuits.

Conclusion

In conclusion, 400LLE2R2MEFC8X9 is a type of aluminum electrolytic capacitor. It is used in many electronic and automotive applications, due to its high reliability and efficient storage capacity. The capacitor is composed of two aluminum foils, an electric double-layer capacitance, and a chemical surface reduction.
