Application Field and Working Principle

E91F351VNT272MCA5T aluminum electrolytic capacitors are used in a wide variety of applications. They are primarily used in power supply filtering and decoupling, DC motors, and audio amplifiers. The capacitor’s primary function is to store energy and then release it in short bursts when needed. The energy is stored in a combination of two layers of aluminum sandwiching a chemically etching and forming a capacitor with a high capacitance to size ratio.

When an AC voltage is applied to the capacitor, electrons are pushed into one of the aluminum layers. This builds up a charge on one side of the capacitor, creating an imbalance of charge between the two sides. This charge imbalance causes a continuous current to flow and a voltage drop across the capacitor until the two sides reach the same potential and the current flow stops, allowing the capacitor to store energy. This is known as the charging process.

The capacitor then releases the stored energy as a DC current when the applied voltage again goes above the potential of the stored charge. This is known as the discharging process. The capacitor is capable of handling relatively high voltages and currents, which makes it ideal for applications such as power supply decoupling, energy storage, and DC motor control.

The capacitor has a range of parameters which determine its performance and characteristics. These parameters include the capacitance, the operating temperature, the rated voltage, the ESR (Equivalent Series Resistance) and the dissipation factor. It is important to ensure that the capacitor is capable of handling the intended application and that the parameters are within the specified ranges.

E91F351VNT272MCA aluminum electrolytic capacitors are available in various sizes and capacitances, allowing the user to select the capacitor best suited for their application. With wide range, high capacitance and excellent reliability, these capacitors are ideally suited for a wide range of applications.
