Aluminum Electrolytic Capacitors are the go-to component of choice for a variety of power-supply applications due to their long life, wide temperature range, and high energy storage capacity. The EEU-FC1A470 is an aluminum Electrolytic Capacitor from Panasonic. It has a robust design that offers reliability and quality performance in a variety of settings and it has long been a darling of the electrician and electronics enthusiast community. This article will serve as a guide to elucidate the applications and working principles of the EEU-FC1A470.

Overview

The EEU-FC1A470 is a radial lead, tubular aluminum Electrolytic Capacitor. It is rated for a voltage of 470V, with a capacitance ranging from 3,000 - 22,000 uF and features an operating temperature of -25°C to +105°C. The EEU-FC1A470 is particularly well-suited to applications requiring long and reliable electrolytic life. With a ripple current rating of up to 10.5 A, and a minimum life of 3000 or 5000 hours at +105°C, the EEU-FC1A470 can provide consistent and durable power support for many years.

Application Field

The EEU-FC1A470 can be used in a variety of power supply applications. As an aluminum electrolytic capacitor, its primary use is in the filter circuit of a rectifier circuit, such as in a power supply for an AC-DC converter. It is also well-suited for use in audio systems, motor speed control circuits, transformers, and other switch-mode power supplies (SMPS). As it is rated for operation across a wide temperature range, it is also suitable for use in portable or high-temperature applications such as medical and automotive applications.

When used in power supply applications, the EEU-FC1A470 can help reduce electrical noise and increase power output efficiency by filtering and smoothing out the ripple voltage generated by the AC power source. As it is rated for a wide range of operating voltage and capacitance values, it allows for flexibility in the design of the power supply. Additionally, its long life, high energy storage capacity, and excellent temperature resistance make it a suitable choice for high-end audio power supplies and other power-sensitive applications.

Working Principle

An electrolytic capacitor relies on the electrolyte used within the device to store charge, and the EEU-FC1A470 is no different. In this case, the electrolyte solution used is a mixture of water, an acid, and a solvent. The acid and the water molecules create the electrolyte, which serves as the dielectric between the two electrodes, the anode and the cathode. When a DC voltage is applied to the capacitor, the inequilibrium of the electrolytic solution creates a charge imbalance, which is stored as electrical energy in the capacitor.

This stored charge then functions to filter out electrical noise on the supply line. The charge stored in the capacitor quickly responds to sudden changes in the load current, which sharply reduces the undesired high-frequency, low-amplitude spikes that can degrade the performance of the power supply. The working principle of the EEU-FC1A470 is similar to that of other electrolytic capacitors, with its robust design and wide temperature range making it particularly suitable for use in a variety of applications.

Conclusion

The EEU-FC1A470 from Panasonic is an aluminum Electrolytic Capacitor that is well-suited for a variety of power supply applications. It has a robust design, long life, high energy storage capacity, and excellent temperature resistance that makes it a popular choice for DC-DC converters, audio systems, and other switch-mode power supplies. Its functional working principle, in which the electrolytic solution within the capacitor is used to store charge, allows the EEU-FC1A470 to filter and reduce electrical noise on the supply line. Applications requiring long and reliable power support will find the EEU-FC1A470 to be a dependable and cost-effective capacitor.
