LGY1K472MELB45

Aluminum electrolytic capacitors are widely used due to their high capacitance value and low cost. They are composed of an anode, a dielectric material, a cathode, and a canister. The anode and cathode are typically made from aluminum foil and electrolytic paper. The most common design, the LGY1K472MELB45, has an electrolyte made from a solution of electrolytes and alcohol.

The LGY1K472MELB45 is a type of polyethylene terephthalate (PET) aluminum electrolytic capacitor. The device has a rated voltage of 16 volts and has a rated storage temperature of -20°C to 105°C. It has a maximum current rating of 25 mA, a capacitance value of 4.7 µF, a voltage dissipation factor (Df) of 0.5, and an equivalent series resistance (ESR) of 9Ω.

The working principle of aluminum electrolytic capacitors is similar to that of other types of capacitors. When voltage is applied across the anode and cathode, an electric field is created. This electric field pulls electrons from the anode into a positively charged polarization region, which results in a build-up of charge in the electrolyte layer. The capacitance of the device is determined by the thickness of the dielectric layer and the size of the area between the anode and cathode.

The LGY1K472MELB45 is primarily used in the automotive, telecommunications, and medical industries. It is often used in power supplies, circuit protection, and signal filtering applications. The device is also used in ACDC converters, boost converters, and DCDC converters.

In summary, the LGY1K472MELB45 is an aluminum electrolytic capacitor that has a rated voltage of 16 volts, a capacitance of 4.7µF, a voltage dissipation factor of 0.5, and an equivalent series resistance of 9Ω. It has a wide variety of applications in the automotive, telecommunications, and medical industries, and is used in power supplies, circuit protection, signal filtering, and converter applications.
