Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are commonly used in electronic circuits due to their relatively large capacitance and low cost. They are available in a wide range of sizes, with capacitances ranging from several microfarads to thousands of farads.

The ALC40A471DE400 is a high-performance, miniature, aluminum electrolytic capacitor with a low Equivalent Series Resistance (ESR). This capacitor is commonly found in power supplies, digital processors, and audio amplifiers. It is designed to provide reliable power and signal conditioning, while delivering excellent performance.

Application Field

The ALC40A471DE400 is often used in power supplies, digital processors, and audio amplifiers. It can be used in circuits where filtered power is required, such as for noise reduction and signal conditioning. It is also suitable for use in pulse-sensitive applications such as servos and motion sensors.

Due to its low ESR, it is ideal for use in load current applications, where the capacitor must handle higher current pulses without the risk of failure. It is also capable of handling large transients, which makes it suitable for use in applications requiring high power delivery.

In addition, the ALC40A471DE400 has a wide range of operating temperatures, making it suitable for use in a variety of applications, including in automotive, avionics, and military environments.

Working Principle

The ALC40A471DE400 is an aluminum electrolytic capacitor, which uses an electrolyte as a medium for storing charge. This capacitor is constructed of two aluminum electrodes, with a paper dielectric sandwiched between them. The two aluminum electrodes are separated by an electrolyte, which is typically a liquid electrolyte or a solid manganese dioxide.

The liquid electrolyte provides a low internal impedance, allowing current to flow through it easily. This low impedance allows the capacitor to handle rapid changes in current, making it ideal for use in high-power circuits.

The paper dielectric keeps the two aluminum electrodes separated, allowing the capacitor to store charge and preventing short-circuiting between them. The paper dielectric also serves as a barrier, preventing the electrolyte from mixing with the aluminum electrodes and dissipating the charge.

When a voltage is applied to the capacitor, electrons begin to flow from one electrode to the other. This flow of electrons creates an electric field within the capacitor, which is responsible for storing charge.

As the charge builds up, the capacitance of the capacitor increases, allowing it to store more energy. This stored energy is then able to be used in a variety of applications, such as powering equipment or components.

The ALC40A471DE400 is able to store charge efficiently, thanks to its low equivalent series resistance (ESR). This low ESR allows the capacitor to handle higher current pulses without the risk of failure.

Conclusion

The ALC40A471DE400 is an aluminum electrolytic capacitor that is capable of providing reliable power and signal conditioning, while delivering excellent performance in a wide range of applications. Its low ESR makes it suitable for use in circuits that require filtered power and can handle high current pulses without failing. Also, its wide range of operating temperatures makes it suitable for use in a variety of environments.
