Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polar electrolytic capacitors developed in the early 1930s, mainly for high-power rectifier circuits, smoothing and energy storage. It has the characteristics of low price, high capacity, small volume, wide application range, good dynamic characteristics and high damping coefficient. These peculiar characteristics make them widely used in permanent electronic circuits such as computers and consumer electronic products.

50YXF1MEFCT15X11 application field and working principle

The 50YXF1MEFCT15X11 is an aluminum electrolytic capacitor with a rated voltage of 100V and a capacity of 2.2μF ±20%. In terms of application fields, it is mainly used as an antiparallel stabilizer for DC power supply, a wetting circuit for low-frequency rectifier, a low-frequency coupling circuit, a low-frequency noise filter, a compensation device for circuit elements, and a delayed circuit.

In terms of its working principle, the following points can be illustrated. Firstly, the inner and outer electrodes are connected in series to form the loop, where the outer electrode is the anode and the inner electrode is the cathode. Secondly, a pole-tight film would be formed on the inner surface of the capacitor to form a thin path. Thirdly, dielectric would be filled between the anode and the cathode and the depth of the gap directly affects the capacitance value. Lastly, aluminum electrolyte liquid would be introduced, and the electrons and ions in the electrolyte liquid allow current to pass through.

Advantages of Aluminum Electrolytic Capacitors

Advantages of aluminum electrolytic capacitors include:

• High capacity in small sizes.
• Used for high current and high power applications.
• Lower cost compared with other types of capacitors.
• Good dynamic characteristics and stable performance.
• High reliability and long service life.

Conclusion

Aluminum electrolytic capacitors, such as the 50YXF1MEFCT15X11, are widely used due to their high capacity and reliability, large application range, low cost, and good dynamic characteristics. Aluminum electrolytic capacitors are used in many applications, including DC power supplies, low-frequency rectifiers, low-frequency noise filters, and circuit element compensation.
