Aluminum electrolytic capacitors are one of the most common types of capacitors used in electrical circuits. They are capacitors consisting of two electrodes separated by an electrolyte, usually an aqueous solution or a solid polymer-based electrolyte. The anode of an aluminum electrolytic capacitor is typically made up of an anodized, rolled oxide aluminum foil which has anisotropic diffusion characteristics. The cathode is typically a metallized polymer film or a solid aluminum foil. The capacitance of an electrolytic capacitor is a function of its surface area, the electrolyte, and the thickness of the oxide layer on the anode.

The VPR112U075N3C is an aluminum electrolytic capacitor which is designed to be used in wide range of applications from audio filters to switching power supplies. It has a rated voltage of 450VAC and a capacitance range of 0.47µF up to 4.7µF. The capacitor features a high dielectric strength which provides good protection against overvoltage and high dielectric absorption which reduces the ripple current.

The VPR112U075N3C has a variety of application fields such as AC line filters, DC blocking, power supply circuits, choke coils, etc. It is also used in high voltage power supplies for UPS, TV, displays, air conditioners, refrigerators, industrial motors, and other home appliances. In these applications the capacitor provides smooth and stable DC voltage and reduces noise generated by the system.

The working principle of the VPR112U075N3C is based on the Faraday Principle. A voltage between the anode and cathode of the capacitor induces a current flow in the electrolyte, which causes the metal ions in the electrolyte to oxidize on the anode. This causes a deposited layer of metal oxides to form on the anode surface which increases the capacitance of the electrolytic capacitor. The oxide layer also isolates the anode and cathode from each other, preventing a short circuit.

The VPR112U075N3C is a reliable capacitor which can be used in a wide variety of applications. Its high dielectric strength and dielectric absorption reduce the amount of ripple current and ensure protection against overvoltage. The Faraday Principle allows it to provide a large capacitance and stability even in high voltage applications.
