Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy storage components that are widely used in DC, AC, high and low frequency electronic circuits. When connected in a circuit, they can filter, couple, smooth, delay, or bypass various signals. They are one of the most widely used electronic components. The capacitance of aluminum electrolytic capacitors can reach thousands or even tens of thousands of microfarads. The voltage range is from the small voltage of 2V to the high voltage of 500V or even higher.

The EKMG100ELL221MF11D is a type of aluminum electrolytic capacitor. This type of capacitor consists of two aluminum foils, a metalized film dielectric and a specially formulated electrolyte. The metalized film dielectric is used to enhance the capacitor’s ability to withstand high voltage, and the specially formulated electrolyte provides a low impedance path between the aluminum foils, ensuring that the capacitor can store and discharge energy quickly and reliably.

Application Field

The EKMG100ELL221MF11D has a broad range of applications due to its high capacitance and voltage range. It is most commonly used in AC circuits and other areas where high capacitance and voltage are needed. They are used in power supply circuits, audio circuits, high power amplifier circuits, oscillator circuits and other high-power equipment.

Working Principle

The working principle of an EKMG100ELL221MF11D is based on the electrochemical phenomenon between two aluminum foils and the electrolyte solution. When a voltage is applied across two aluminum foils, anions move from one side to the other, increasing their concentration on the positive pole, resulting in a build-up of positive charge. This positive charge attracts negative electrons from the other side, resulting in a buildup of negative charge. This process creates an electric field, which is stored in the aluminum electrolytic capacitor as electrostatic energy.

The electric field in the aluminum electrolytic capacitor can be maintained as long as the voltage applied across its terminals remains above a certain threshold. When the voltage is removed, the electric field dissipates and the capacitor returns to its initial state.
