Aluminium electrolytic capacitors are a variety of capacitors with a high capacitance density. These capacitors are increasingly used in power electronics and consumer electronics applications due to the enormous advantages they provide over other types of capacitors. The EEU-FC2A100E is a type of aluminium electrolytic capacitor from Panasonic, which is rated for a DC voltage of 100V.

Application Field

Aluminium electrolytic capacitors are ideal for a variety of electronic applications, such as DC-DC converters, power supplies, frequency converters, and motor drives. They can also be used in transistors, switching power supplies, and other high-frequency applications. They are used in these applications because they are able to handle larger currents and provide a good efficiency of voltage conversion.

The EEU-FC2A100E is a radial and axial leaded, snap-in type aluminium electrolytic capacitor, with a terminal pitch of 16mm, making it suitable for applications requiring high currents and high stability. It has a maximum ripple current of 2500μA, making it suitable for power supplies and high power audio amplifiers. It also has a low equivalent series resistance (ESR) of 0.16Ω, which provides an excellent power efficiency.

Working Principle

Aluminium electrolytic capacitors work on the principle of electrolysis. They use two aluminium foils, an electrolyte solution, and a porous separator which are stacked together. The aluminum foils are etched with a pattern of holes and coated with a thin layer of oxide. This oxide layer acts as a dielectric. One of the aluminium foils is connected to the positive side of the capacitor, while the other is connected to the negative side.

The electrolyte solution is then injected into the capacitor. This solution provides a medium in which ions can move, allowing a current to flow. The ions move across the aluminium-oxide layer, creating a charge separation which stores the energy. This effect creates a high capacitance in the capacitor. As the voltage increases, the electric field between the charged plates increases as well, causing more ions to move.

The capacitance of the EEU-FC2A100E capacitor can be further increased by stacking multiple units in parallel. This allows the capacitor to handle higher currents, which makes it ideal for applications with high power requirements.

Aluminium electrolytic capacitors are the preferred choice for many power and audio applications. They offer high capacitance and the ability to handle high currents. The EEU-FC2A100E is an excellent choice for applications that require high power and high stability.
