Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are passive components used for energy storage and signal filtering, among other uses. A typical aluminum electrolytic capacitor consists of an anode (positive electrode) made of aluminum foil, a solid electrolyte made of paper casing, and a cathode (negative electrode) that also serves as a terminal. The two electrodes are separated by a thin barrier called the dielectric, which allows the capacitor to store an electric charge.

The 450PK4R7MEFC10X12.5 aluminum electrolytic capacitor is a type of polarized capacitor, meaning that it has a positive and negative terminal, with the anode being the positive terminal. It has a maximum working voltage rating of 450V, which is one of the highest available among aluminum electrolytic capacitors. Additionally, it can handle up to 2.5A of current without any significant performance degradation. It is also highly stable, meaning that its capacitance remains constant over time and is unaffected by temperature or frequency changes.

Application Field and Working Principle

The 450PK4R7MEFC10X12.5 aluminum electrolytic capacitor is suitable for many high-voltage applications, including in power supply systems, inverters, and motor drivers. Additionally, it can be used in audio-video applications, such as in amplifiers and loudspeakers, as well as for driving high-frequency relay coils. The wide range of applications of this capacitor is due to its high voltage and current-handling capabilities, as well as its high stability.

The working principle of this aluminum electrolytic capacitor is based on Faraday\'s law of induction. This law states that when an electric field is applied to the dielectric, the electric field generates a magnetic field and causes current to flow between the electrodes. This flow of current in the capacitor forms an electric charge, which can be utilized in various applications.
