ALF20G391EE450

Aluminum Electrolytic Capacitors (AECs) are one of the most commonly used electronic components in electronic circuits. AECs have a wide range of applications, ranging from high frequency, high ripple current and very low equivalent series resistance (ESR) to large capacity and impedance. The ALF20G391EE450 is an example of an AECs that is able to provide an excellent combination of features and thus is suitable for a variety of applications.

The ALF20G391EE450 is a capacitor module that features an aluminum electrolyte die-formed capacitor for use in applications requiring low equivalent series resistance, high ripple current and impedance. It is designed to handle high frequency applications up to 4000 Hz, with maximum rated voltage of 200 volts and capacitance of 39 µF, and an extra capacitance of 2.3 µF. It is an electrolytic dual-layer capacitor that can handle high current, high ripple current and high temperature applications. This makes it often ideal for use in power supplies, amplifiers, and other frequency-critical circuitry.

The ALF20G391EE450’s working principle is based on the fact that electrolyte die-formed aluminum capacitors feature an anodized aluminum foil between a pair of insulating layers (or “bonded papers” as it is sometimes referred to) resulting in a component that can handle high ripple currents over a wide range of operating conditions. The dielectric, die-formed aluminum, consists of multiple layers of film sandwiched between two solid electrolyte layers. When an electrical source is applied to the capacitor, an electrolyte solution in the electrolyte layers begins to ionize, forming a very thin film of electrolyte between the anodized aluminum foil and the dielectric layers. This thin film of electrolyte serves as an insulator between the anodized aluminum film and the dielectric layers, resulting in a capacitor with a low ESR, high ripple current, and high temperature capability.

By combining a die-formed aluminum capacitor film with an extra capacitance of 2.3 µF, the ALF20G391EE450 is able to provide an excellent combination of features and thus is suitable for a variety of applications. Applications include power supply, audio amplifiers, and other high frequency related circuitry. Its low ESR and high ripple current capabilities are suited for both high frequency and high temperature environments.

In conclusion, the ALF20G391EE450 is a highly useful AEC that combines multiple layers of die-formed aluminum capacitors with an extra capacitance of 2.3 µF in order to provide an excellent combination of features. Its low ESR, high ripple current, and high temperature capabilities make it suitable for a variety of high-frequency applications such as power supplies, audio amplifiers, and other frequency-critical circuitry.
