• Working Principle

The RFS-16V470MG3#5 aluminum electrolytic capacitor mainly adopts the structure of three layers: two aluminum foil electrodes, one aluminum oxide film and one filter paper with high insulation performance, which are laminated respectively. The surface of aluminum foil electrode is coated with electrolyte and surrounded by the filter paper. The aluminum foil electrode is coated with a very thin, porous and insoluble aluminum oxide film, and then clamped together by the filter paper.In the process of working, a certain potential difference can be generated by the two layers of aluminum foil electrodes. Since the aluminum oxide film has a high dielectric constant and the thin porous structure can be filled with electrolytic solution, a large capacitance can be generated between the two electrodes.In addition, the semiconductor characteristics of electrolytic solution can provide equivalent resistance between the two poles of the capacitor, which can filter and buffer the input current through capacitive effect. At the same time, because of the high insulation performance of the filter paper, it also ensures the safety and reliability of the capacitor.

• Conclusion

The RFS-16V470MG3#5 aluminum electrolytic capacitor has a wide range of applications in electronic equipment related to the communication industry, power supply, computing equipment, television, DVD, medical instruments and so on. Its working principle lies in that the two layers of aluminum foil electrodes coated with electrolyte and surrounded by the filter paper produce a certain potential difference, so as to generate a large capacitance between the two electrodes. In addition, the semiconductor characteristics of electrolyte and filter paper also ensure the safety and reliability of the capacitor.
