Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components used in electronics that are filled with an electrolyte, which stores charge in electrical circuits. They are often used as part of an oscillator circuit to keep oscillations of a given frequency. With their high capacity and low ESR (Equivalent Series Resistance) they are extremely useful components for an electronic system.The 476SAK025M is an aluminum electrolytic capacitor from Murata Electronics, and is designed to give a long life and excellent value. It is a radial-type capacitor, with a wide variety of applications in electronics, and it is an important component for all manner of power management applications.

476SAK025M Application Field and Working Principle

The 476SAK025M is an aluminum electrolytic capacitor designed for use in a variety of automotive and consumer electronics applications, such as car audio systems, DC-DC converters, and voltage regulation. It is also suitable for applications in industrial and medical equipment.The 476SAK025M has an operating temperature range of -40°C to +105°C, and consists of an anodized aluminum casing, into which an electrolyte is sealed. It has a rated voltage of 25V, and a rated capacitance of 47uF. It is a non-polarized device, meaning that there is no need for a marking on the ends of the casing to indicate the polarity.The working principle of an aluminum electrolytic capacitor is fairly simple. It consists of two layers of electrodes separated by an electrolyte, a liquid usually based on organic solvents such as benzene or ethylene glycol. When electrical energy is applied to the electrodes, the electrolyte ionizes, allowing electric current to flow through and charge the capacitor. Since the electrolyte is an insulator, an electric charge is able to build up between the two electrodes, forming a capacitor.The 476SAK025M is designed for a long life and excellent value, so the electrolyte used is carefully formulated to ensure it has a high dielectric strength and low leakage current. This helps to maintain a consistent capacitance and ensure a long service life.

Conclusion

The 476SAK025M is a radial aluminum electrolytic capacitor designed for high capacity and low ESR applications. It is used in a wide variety of automotive and consumer electronics applications, and is popular for its long life and excellent value. It operates based on the simple principle of charge separation, and the carefully formulated electrolyte helps to maintain a consistent capacitance and a long life.
