Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are polarized capacitors with very large capacitance values per unit volume, making them desirable for use in high-energy density applications. The 50PX220MEFCT810X12.5 capacitor in particular is an axial-lead type capable of resolving input filter ripple current up to a maximum voltage of 1V and temperature up to 85 degrees Celsius.

Application Field

The 50PX220MEFCT810X12.5 capacitor is useful for many different purposes. It is specifically designed to serve as an input filter cap for various types of power modules, improving the current stability of the power supplied by a DC power module. It can also be used to filter out noise and harmonics in electric power systems, due to its high capacitance and low impedance. Additionally, it can be employed in various audio and video systems, such as in the power supply of devices such as TVs, radios and projectors.

Working Principle

The capacitor works by storing electrical charge in two aluminum foil panels, which are separated by a waxed paper and an electrolytic solution. This creates an electric field between the plates, causing an electrical voltage to manifest between them when current is applied. The amount of current is determined by the capacitance value of the capacitor, as this determines the amount of charge stored. As the current is applied, the voltage present in the capacitor will increase, creating a charging effect.

When the capacitor’s current exceeds a certain level, the device will experience a breakdown phenomenon where the electrical field across the plates becomes too strong. This can cause a short circuit, and is referred to as dielectric breakdown or failure. It is important to note that due to their polarized construction, aluminum electrolytic capacitors should be installed correctly in order to prevent this from happening.

Conclusion

The 50PX220MEFCT810X12.5 Aluminum Electrolytic Capacitor is an incredibly useful tool for many different audio, video and power filtration applications. Its high capacitance and low impedance make it perfect for filtering out noise and harmonics, and it is able to perform consistently under a variety of temperatures and voltages. Furthermore, by understanding its basic working principle and having a basic knowledge of how to correctly install it, this device can be used to improve the power supplied by many different types of systems.
