Aluminum electrolytic capacitors are one of the most common and widely-used types of capacitors. They are used for a huge variety of applications, from high-frequency circuits to power supplies and audio circuits. The 400USG470MEFC25X50 is an aluminum electrolytic capacitor specifically designed for use in applications requiring high frequency and low impedance, like flash memories, switched-mode power supplies, and power management systems.

Composition & Construction

The 400USG470MEFC25X50 aluminum electrolytic capacitor is made up of an anode wrapping, a cathode wrapping, and electrolyte liquid filling. The surface of the anode is oxidized, forming a very thin layer of oxide that is known as the dielectric. This oxide dielectric is then covered with a thin aluminum foil, which acts as the cathode. The electrolyte liquid filling provides the necessary electrical insulation between the two substances.

The two-winding construction of the 400USG470MEFC25X50 provides a high capacitance value within a small case size, making it suitable for applications with limited space. The capacitor is also designed to operate well in high temperature and high-frequency applications, making it a great choice for power management systems and flash memory components.

Working Principle

The 400USG470MEFC25X50 works on the principle of electrical polarization. When a DC voltage is applied to the two-winding construction, the anode will be positively charged while the cathode will be negatively charged. This will create a static electric field between the two, which will cause the two substances to become electrically charged and attract each other. As this attraction takes place, the capacitance and voltage rating of the capacitor will increase.

The 400USG470MEFC25X50 is designed to operate at a moderately low-frequency range, usually between 10KHz and 200KHz. This makes it especially useful for high-frequency operation devices, such as flash memories, where high-frequency currents flow regularly. This frequency range also makes it an attractive choice for power management systems, as it allows for quicker responses and reductions in current.

Application Field

The 400USG470MEFC25X50 is a great choice for applications that require high frequency and low impedance. Specifically, it can be used in flash memory components and power management systems. It can also be used in high frequency circuits requiring stable capacitance, and in switch-mode power supplies. It is also an excellent choice for audio circuits, where it provides protection and stability.

The 400USG470MEFC25X50 is highly reliable, due to its construction and aluminum electrolytic design. It is an attractive choice for many high-frequency and power management applications, due to its small size, low impedance, and high capacitance. As such, it is a great choice for a wide variety of applications.
