Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used components in electronic circuits due to their excellent performance and cost-effectiveness. These components are ideal for applications requiring a high-frequency current, such as switching power supplies, digital signals processing, and audio systems. The B43455A4688M000 is a popular aluminum electrolytic capacitor that offers reliable performance for various kinds of circuits.

Application Field

The B43455A4688M000 aluminum electrolytic capacitor is ideal for general-purpose applications where the maximum voltage and capacitance are not specified. It is suitable for circuits with a high frequency or switching current and can be used for AC or DC circuits. For applications which require high stability, low leakage current and long life, with the capacity of 4,688µF and rated voltage of 63V, this capacitor is a great match.The B43455A4688M000 aluminum electrolytic capacitor is suitable for use in temperature and humidity measurement devices, electronic dampers, resonance circuits, digital and linear power amplifiers, switching power supplies, and audio-frequency amplifiers. It is also suitable for radio-frequency circuits, such as radio receivers and shortwave stations.

Working Principle

The working principle of the B43455A4688M000 aluminum electrolytic capacitor is based on the electrochemical properties of aluminum. When two aluminum foils are immersed in an electrolyte, a voltage is applied to one of the foils. This creates a double layer of charge on the surface of the aluminum foil, forming a capacitance (or dielectric). As the voltage increases, more layers of charge are created and the capacitance increases.The electrolyte also plays an important role in increasing the capacitor\'s capacitance. It is usually a gel-like material that is deposited on the surface of the capacitor. This material acts as an insulator, preventing the electricity from passing through and allowing it to accumulate on the surface of the aluminum foil. This results in a higher capacitance and allows the capacitor to store more electrical energy.In addition to its capacitance, the B43455A4688M000 aluminum electrolytic capacitor also has a low ESR (equivalent series resistance), making it well-suited for high-frequency applications. The voltage applied to the capacitor must be strictly regulated in order to ensure a sufficient voltage to reach the components and to prevent the capacitor from being damaged due to excessive current passing through the capacitor.

Conclusion

The B43455A4688M000 aluminum electrolytic capacitor is a great choice for applications that require reliable performance and a high frequency. It is well-suited for use in temperature and humidity measurement devices, resonance circuits, digital and linear power amplifiers, and other types of circuits. Its excellent capacitance and low ESR make it an ideal choice for high-frequency applications.
