Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used types of capacitor in electronic circuits. These capacitors are popular due to their large capacitance and low cost. The EKXJ201ELL151MK35S is an aluminum electrolytic capacitor with a voltage of 16-50V and a capacitance of 47µF.

Application Field

The EKXJ201ELL151MK35S aluminum electrolytic capacitor finds application in consumer electronics, instrumentation, lighting, medical equipment, and other industrial applications. It is used for decoupling, coupling, energy storage, filtering, and signal processing. These applications require high capacitance and low leakage current, which the capacitor provides. It is also used in radio frequency (RF) applications to provide gain and tune circuits. The capacitor can also be used for power supplies, such as in the power factor correction circuit of battery chargers or to filter power supply noise in low power devices.

Working Principle

The EKXJ201ELL151MK35S aluminum electrolytic capacitor utilizes an electrolyte medium to store electrical energy. The capacitor is composed of two aluminum foils located at opposite sides of the medium, separated by a dialectic material. One of the foils acts as the anode, and the other as the cathode. The anode is coated with a thin layer of an oxide layer. The electrolyte is usually a gel or a liquid filled with ions.

When the capacitor is connected to a voltage source, the anode starts to attract the positive ions, while the cathode attracts the negative ions. This creates an electric current through the capacitor, which accumulates charges on both sides. The voltage across the capacitor increases slowly, allowing it to store electrical energy. When the voltage across the capacitor reaches the same magnitude as the supply voltage, the voltage across the capacitor remains at a constant. The current through the capacitor stops, but the stored energy is retained.

With this simple working principle, the EKXJ201ELL151MK35S aluminum electrolytic capacitor can provide steady voltage and steady current. Its capacitance and rating provide reliable performance in most applications, especially in high-frequency filtering and switching circuits.
