Application Field of ALF20G471EE400

The ALF20G471EE400 is a great choice for power electronic circuits, especially for low-frequency power ranging from 50Hz to 400Hz. It is also popular for audio amplification and filtering applications since its low equivalent series inductance is also suitable for high frequency switching circuit. It stands out in switching power supplies, frequency converters, and UPS systems because of its low equivalent series resistances. It also has a long service life and low outgassing rate.

Working Principle of ALF20G471EE400

The ALF20G471EE400 is based on the principles of electrostatics and the electrolyte-filled dielectric material. It is mainly composed of two electrodes, a solid anode, and a porous cathode, which are both immersed in an electrolyte. The oxide film formed on the anode is the dielectric material that provides an electric field for capacitance.

The two electrodes are connected with an external circuit and when the power is applied, the negative electrons in the circuit will flow into the anode while the positive charges will flow into the cathode, producing a static electric field. This generates an opposing current and generates a capacitance, which stores energy as an electric field.

The ALF20G471EE400 capacitors have several great features that make them very efficient. It has an advanced construction design that makes it highly resistant to reverse polarity and voltage surge, non-polarity, and high temperature and pressure. The anode foil and the capacitor housing are covered with a special dielectric film that further enhances its performance, and ensures a long service life.

Apart from these features, they are also ideal for use in a wider variety of applications since they have low ESR, improved leakage current, and excellent heat dissipation. The ALF20G471EE400 also has a long shelf life and is resistant to environmental factors, such as moisture, vibration, dust, and shocks, making them very reliable.

Conclusion

The ALF20G471EE400 Aluminum Electrolytic Capacitor is an ideal choice for use in high voltage applications, especially in low-frequency power and audio applications. It has excellent features that makes it highly efficient and make it great for all kinds of applications. With a high degree of reliability and a long service life, the ALF20G471EE400 is an excellent choice for use in power electronic circuits.
