Aluminum Electrolytic Capacitors are an indispensable part of electronic circuits. They are mainly used for DC filtering, such as power filters, DC-DC converters, and storage for the instantaneous peak current of many occasions. In many occasions, the surface mount aluminum electrolytic capacitors satisfy current demand. The EEU-FM1V471 is an example of an SMD (surface mount device) aluminum electrolytic capacitors. Understanding its application field and working principle provides users with the necessary knowledge to deploy this particular Capacitor.

Application Field of EEU-FM1V471
The EEU-FM1V471 Aluminum Electrolytic Capacitors from Omron are ultra-small capacitors with an increased performance and an increased reflow suability. EEU-FM1V471 are available in capacitance range of 4.7μF and tolerance to ±20%. They are employed in a variety of electronic circuits whenever a small size, high reliability and a long lifetime are required. A few of the applications include DC-DC converters, AC filters, power supply and other dedicated line filters. It is also used as primary and secondary sides of the stabilizers, secondary filters for car audio systems, and many other circuit configurations.

Working Principle of EEU-FM1V471
The working principle of an aluminum electrolytic capacitor is based on the formation of an electric double layer inside the capacitor. This happens when a polarization voltage is applied to the capacitor across its two terminals. An electric field is generated between these two terminals, creating an electric charge on the surface of an electrolyte separator. This electric charge is stored in the form of a double layer of ions on the capacitor\'s plates. This electric double layer will remain charged until the capacitor is discharged.The capacitance of an aluminum electrolytic capacitor depends on the surface area of the aluminum cathode, the ions concentration of the electrolyte, and the polarization voltage of the capacitor. The EEU-FM1V471\'s low ESR and low leakage current make it ideal for applications where high stability and reliability are required. The reduced ES and leakage current enable the capacitor to operate at reduced temperatures compared to standard electrolytic capacitors. The capacitance characteristics are also consistent over a wide temperature range, from -40°C to +105°C.

The EEU-FM1V47P aluminum electrolytic capacitor is an ideal choice for high-density electronic circuit design which requires high reliability and long lifetime. Thanks to the improved reflow compatibility, the EEU-FM1V471 can be reflow soldered without any detrimental effect. Its small size and high capacitance make it perfect for DC and AC filters, power supplies, and other dedicated line filters. With the help of its superior leakage current and capacitance consistency, the EEU-FM1V471 is able to perform in high-temperature environments as well.
