Aluminum electrolytic capacitors are an important type of capacitors and are extensively used in a wide range of electrical and electronic applications including power supplies, audio equipment, and signal processing equipment. The EEU-FR1C471B, in particular, is a popular aluminum electrolytic capacitor produced by Panasonic. It is often used for surge absorption, motor control, and other related applications, thanks to its excellent features such as low ESR, high ripple current capability, long life, and wide temperature range.

The EEU-FR1C471B is a radial lead-type aluminum electrolytic capacitor with a capacity of 4.7 μF (microfarads). It has a rated voltage of 25V, an operating temperature range of -40°C to +105°C, and a rated tolerance of ±20%. It also has a leakage current of 0.03CV (where C is the rated capacitance) and a dissipation factor of less than 0.15%. Additionally, the EEU-FR1C471B has a rated endurance of 2000h at +105°C, with a maximum ripple current of 12Ap-p (at +105°C).

The working principle of aluminum electrolytic capacitors is based on Faraday’s law of electrolysis. When current passes through the capacitor, a reaction occurs between the aluminum anode and the electrolyte, forming aluminum oxide inside the capacitor. This aluminum oxide acts as an insulating layer and allows for the formation of a capacitor. The capacitance of the aluminum electrolytic capacitor is determined by the amount of capacitance stored by a given layer of aluminum oxide. This capacitance is typically in the range of 1 to 10 μF.

The EEU-FR1C471B is particularly useful for applications requiring high reliability and low ESR such as motor control, audio circuitry, power supplies and signal processing. Its low ESR, high ripple current capability and long life make it ideal for these types of applications. Furthermore, its wide operating temperature range of -40°C to +105°C makes it suitable for use in harsh environments.

In summary, the EEU-FR1C471B is a highly reliable aluminum electrolytic capacitor with excellent features. It can be used for surge absorption, motor control and other related applications, thanks to its low ESR, high ripple current capability, long life and wide operating temperature range. The capacitor’s working principle is based on Faraday’s law of electrolysis and its capacitance is determined by the amount of capacitance stored by a given layer of aluminum oxide. Overall, the EEU-FR1C471B is an excellent choice for a wide range of electrical and electronic applications, where reliability and features are of utmost importance.
