Aluminum Electrolytic Capacitors are ideal for electronic applications that need a large amount of storage capacity and perhaps long-term stability. They can also be used as a power supply in some cases, due to their high-energy density. Aluminum Electrolytic Capacitors have an overall capacity of approximately 200F per watt.

450PX2.2MEFC8X11.5 Application Field and Working Principle

The 450PX2.2MEFC8X11.5 aluminum electrolytic capacitor is a type of polarized aluminum electrolytic capacitor that features long life and excellent moisture resistance. It is designed for use in high-voltage applications such as aircraft, DC motor drives, military equipment, electronic transformers, and AC motor drives. It is suitable for high temperature and high ripple current applications due to its constructed with aluminum that has been epoxy sealed onto an aluminum oxide dielectric.

The working principle of the 450PX2.2MEFC8X11.5 aluminum electrolytic capacitor is based on the Faraday law of electrolysis. In this law, when an electric current is passed through an electrolyte, it causes electrochemical reaction to occur at both the electrodes, resulting in the removal of a metallic ion from one electrode to the other. This causes an electric field to be applied to the metal electrodes, resulting in polarization. This polarization effect creates a dielectric barrier which blocks the flow of electric current between the two electrodes.

When the capacitor is connected in an AC circuit, the electric current flows through it in a series-parallel fashion. As the AC voltage increases, the capacitor charges up and stores energy until it reaches its maximum capacitance. This stored energy is then released into the circuit as the voltage drops. The maximum stored energy of the capacitor is determined by the maximum capacitance, as stated by the Faraday law.

The rated capacitance of the 450PX2.2MEFC8X11.5 aluminum electrolytic capacitor is 450 microfarads (μF) with a nominal voltage rating of 2.2 VDC. It has a rated ripple current of 65 Amps, a leakage current of 11.5 milliamps, a dielectric strength of 1240 VDC, and an insulation resistance of 10000 MΩ. The capacitor is polarized and it also has a short circuit safeguard to protect against any possible short circuit.

The aluminum electrolytic capacitor has a wide range of applications. It is used for DC filtering, high voltage motor drive circuits, pulse transformers and snubbers, and energy storage and isolation applications. In addition, it can also be used in audio crossover networks, power supplies, and audio transformers.

In summary, the 450PX2.2MEFC8X11.5 aluminum electrolytic capacitor is a reliable, long lasting, and energy efficient capacitor. Its long life and excellent moisture resistance make it suitable for high voltage applications. It also has a wide range of applications, such as DC filtering, audio crossover networks, and pulse transformers. The working principle and application of the capacitor is based on the Faraday law of electrolysis and provides reliable energy storage and isolation.
