Aluminum electrolytic capacitors are components commonly used in most electronic equipment. The VPR451U075N1L is a type of aluminum electrolytic capacitor commonly used. Let us know the application, field and working principle of this kind of capacitor.

The VPR451U075N1L aluminum electrolytic capacitor belongs to the VPR class of capacitors. This kind of capacitor is mainly used in high frequency circuit, and widely applied in television sets, audio equipment, computers and other output filters inter-stage circuits. Besides, it features the characteristics of high temperature resistance, high reliability and low equivalent series resistance.

The VPR451U075N1L aluminum electrolytic capacitor consists of an aluminum shell and an aluminum inner core, two electrodes and two seals. It obtains capacitance as a result of electrochemical reaction between electrolyte and aluminum.

The working principle of VPR451U075N1L aluminum electrolytic capacitor is that it is charged by polarizing voltage between its two electrodes, based on electrolyte and aluminum film with surface oxide electronic double layer capacitance generated between them. The surface of electrolyte and aluminum core are polarization layers, which polarize the other layers to double layers, so forming the dielectric capacitance.

In high temperature environment, VPR451U075N1L aluminum electrolytic capacitor can work steadily without external force. If the current to be passed through the capacitor exceeds the rated peak current, the capacitor will be damaged.

In summary, the VPR451U075N1L aluminum electrolytic capacitor is widely applied in television sets, audio equipment, computers and other output filters inter-stage circuits because of its high temperature resistance, high reliability and low equivalent series resistance. Moreover, the working principle of this kind of capacitor is based on electrolyte and aluminum film with surface oxide electronic double layer capacitance generated between them.
