Aluiminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in many electronic applications and are known for their excellent stability, robustness and low leakage performance. These capacitors are typically constructed from a metallic aluminum oxide dielectric material, which stores energy in an electric field and acts as a charge carrier. In addition, they provide high capacity and are suitable for use in a variety of applications, such as power converters, power supplies, audio circuits, radio frequency (RF) circuits and signal processing.

The EKMS201VSN391MP25S is a surface-mount, aluminum electrolytic capacitor from Murata Electronics. This capacitor uses a laminated aluminum oxide dielectric surrounded by a sealed aluminum shell, and is rated for a maximum voltage of 16V. It has a nominal capacitance of 2.2uF with a minimum capacitance of 1.905uF and a maximum capacitance of 2.39uF. The EKMS201VSN391MP25S has a small size and is suitable for use in a variety of electronic devices, particularly those in which board space is at a premium. The EKMS201VSN391MP25S has several benefits that make it ideal for applications requiring an efficient storage and rapid dissipation of electrical power. Its low equivalent series resistance (ESR) helps reduce electrical noise and enables smoother operation, and its low self-inductance minimizes the impact of power changes on the component, making it suitable for a variety of applications. Additionally, the capacitor is rated for a maximum operating temperature of 85°C, ensuring reliable operation in high temperature environments.

The working principle of the EKMS201VSN391MP25S is based on the same underlying principles as all aluminum electrolytic capacitors. Aluminum metal plates, separated by a thin insulating oxide film, act as the two plates of a capacitor. Connected to the aluminum plates are an anode lead and a cathode lead, which together form the capacitor’s terminals. When a voltage is applied across the terminals, a current flows through the capacitor, and the oxide film between the two plates becomes charged. This charges creates an electric field between the plates, which stores energy in the form of an electrical charge. This stored energy is then released when the capacitor is discharged, allowing for the efficient storage and dissipation of electrical power.
