Aluminum Electrolytic Capacitors

A popular type of capacitor is the aluminum electrolytic capacitor, also known as an aluminum electrolytic capacitor, which is used in many different applications, including power supplies, instrumentation, and audio and video equipment. It is composed of a dielectric or electrolyte material with a dielectric constant determined by its composition, and concentrated metal electrode plates. The aluminum electrolytic capacitor, coded 16YXF470MEFCT810X12.5, is a classic example of this type of capacitor.

Application Fields

The aluminum electrolytic capacitor 16YXF470MEFCT810X12.5 has two major application fields, the first being a power supply. In a power supply, the capacitor is typically used to absorb energy spikes and reduce harmonics in the power supply. This is done by providing a low-impedance path that allows the high-frequency energy to bypass the components of the power supply. This reduces the amount of noise and interference in the system.

The second major application field is instrumentation. In many cases, the capacitor is used to eliminate electrical noise, limit EMI, ensure a steady power supply, and protect against corrosion. It is also used in signal processing to increase both the power and signal-to-noise ratio of the circuit. This type of capacitor can also be used in audio and video equipment to provide clean power for the system.

Working Principle

The aluminum electrolytic capacitor is composed of two concentric metal plates, known as an anode and cathode, separated by an electrolyte. The anode is the positive electrode, and the cathode is the negative electrode, and the electrolyte is a substance that conducts the electric current. The dielectric constant of the capacitor is determined by the composition of the electrolyte.

When a voltage is applied to the capacitor, a current flows between the anode and cathode. The current causes electrolysis, which in turn forms an oxide film on the surface of the anode. This oxide film acts as a dielectric material, holding a significant electrical charge. The amount of charge held is determined by the capacitance of the component.

The capacitor also has a leakage current, a small amount of current that flows even when the capacitor is not connected to a voltage source. This is due to the wire connections or through the oxide film. This allows for the current to pass even when the voltage on the capacitor is zero.

The aluminum electrolytic capacitor 16YXF470MEFCT810X12.5 finds widespread application in a variety of applications due to its ability to absorb energy spikes and reduce harmonics, provide a steady power supply, eliminate electrical noise and interference, and protect against corrosion. Its combination of a high capacitance and a low leakage current makes it an ideal choice for many types of power supply and instrumentation applications.
