Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AELC) refer to capacitors that use a combination of aluminum foil and electrolyte as the dielectric for its electrodes. The structure of an AELC consists of an anode, which is an oxide layer of aluminum foil, and a cathode, which is made of a metal foil and immersed in an electrolyte. The oxide layer of aluminum foil acts as the dielectric that is responsible for holding a charge and when it is combined with electrolyte, it will raise its capacitance even higher. AELCs are used in multiple applications such as filtering, energy storage, or timing devices due to its high capacitance, low equivalent series resistance (ESR), and low price.

UBY1V472MHL Application Field and Working Principle

The UBY1V472MHL is a 1812-sized aluminum electrolytic capacitor from Nichicon series UBY. This capacitor is characterized by its high B-value, rated voltage up to 5.6 Volts, and low leakage current. It is an axial-lead type capacitor and features a snap-in design for easy installation and integrated load life indicator for added safety. This capacitor is ideal for use in electrical circuits where it exhibits excellent performance in filtering, energy storage, and timing applications. Its capacitance stability and ESR remain constant even after prolonged operating time.

The operating principle of the UBY1V472MHL aluminum electrolytic capacitor is based on the combination of aluminum foil and electrolyte. It consists of a solid aluminum anode and a porous aluminum cathode in which an electrolyte is inserted. This electrolyte, usually containing acid, allows current to pass through the anode and then dissolves the positive ions of that anode into the electrolyte which helps to form a vacuum-like state between the anode and cathode. This in turn creates a very strong electric field across the two sides of the capacitor, which holds charge in the electric fields and prevents discharge until the capacitor is triggered to do so through some electrical signal.

The UBY1V472MHL aluminum electrolytic capacitor is a great choice for projects requiring highly stable capacitance levels and low equivalent series resistance (ESR). It is also well suited for different types of applications such as filtering, energy storage, and timing where its low leakage current offers additional security and protection. Moreover, its high B-value and rated voltage up to 5.6 Volts make it a reliable and long-lasting solution for various applications.
