Aluminum electrolytic capacitors refer to capacitors consisting of a cathode (anode) made of aluminum foil and a metal oxide film formed on the surface of the anode (cathode). Using an electrolyte solution, a porous oxide film is formed on the anode surface (cathode) of an aluminum foil electrolytic capacitor to form an electric double layer electrolytic capacitor. In the application area and working principle of SH472M016ST aluminum electrolytic capacitors, its application areas are power electronic products, communication products, medical equipment, civil electronics, and military electronic products, among which power electronic products are the most common, such as UPS systems, inverters, welding machines, audio electronics, FPD backlight power, Industrial automation, etc.

The working principle of SH472M016ST aluminum electrolytic capacitor is as follows: when the aluminum foil is used as the anode, a porous oxide film is formed on its surface by electrolyzing the electrolyte, so that it can act like a dielectric, while the outer surface is electrolyte liquid, so a capacitance occurs when connecting to the circuit. At the same time, because of the chemical features of the solution, it will protect the device from electricity, and serve as a signal filter. This is the basic principle of capacitor structure.

The SH472M016ST aluminum electrolytic capacitor is a polarized capacitor. Its anode and cathode terminals are clearly marked, which is very important for the correct operation of the capacitor. When the voltage applied across the capacitor is reversed, the oxide film formed on the anode may collapse suddenly, resulting in an internal short circuit, which may cause fire or other disasters. Therefore, the anode and cathode terminals must be identified correctly, and the capacitor should not be subjected to reverse voltage. Furthermore, the application temperature of SH472M016ST should not exceed the rated temperature to ensure its safe and reliable operation. The capacitance may also change due to temperature, so the application temperature must be taken into consideration.

In conclusion, SH472M016ST aluminum electrolytic capacitors are widely applied in power electronic products, communication products, medical equipment, civil electronics, and military electronics. Its working principle is based on the formation of a porous oxide film on the anode surface by electrolyzing an electrolyte solution, so that it can act like a dielectric, and provide signal filtering, while its anode and cathode terminals must be identified correctly to avoid electric leakage and fire danger. Finally, the application temperature of the SH472M016ST should not exceed its rated temperature to ensure its safe and reliable operation.
