Aluminum Electrolytic Capacitors: UUJ2E470MRQ1MS Application Field and Working Principle

Aluminum electrolytic capacitors are electronic components used to store electric charge, which are widely used in a variety of electrical equipment. The UUJ2E470MRQ1MS series of aluminum electrolytic capacitors is developed and manufactured by KEMET, which can be used for various applications with superior safety, performance, and extended life.

What is an Aluminum Electrolytic Capacitor

An aluminum electrolytic capacitor is an electronic component composed of two electrodes with a non-conductive material inbetween, usually a dielectric medium. It is constructed with a cylinder containing both a porous semi-solid metal anode and a liquid electrolyte, which maintain an electrical charge. The anode can be composed of an aluminum foil, and the electrolyte can be composed of a chemical solution such as ethylene glycol, which is then sealed with wax or epoxy resin. This provides the capacitor with the ability to store electrical charge, which can be used for a number of electronic applications.

Applications of UUJ2E470MRQ1MS Series

The UUJ2E470MRQ1MS series of aluminum electrolytic capacitors is designed for use in automotive and consumer electronics. These capacitors are designed for an operating temperature range of -40 to +105°C, which makes them suitable for use in environments where higher temperatures are encountered. Furthermore, these capacitors have a long life expectancy of up to 10,000 cycles, ensuring a reliable component for long-term use.In automotive applications, the UUJ2E470MRQ1MS series is used for starter motors, alternators, power windows, headlights, and custom audio/video systems. Additionally, these capacitors can be used in consumer electronics such as cellular/mobile phones, TVs, DVD players, laptop computers, video game consoles, and portable music players.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the movement of ions from one electrode to the other. When the capacitor is energized, the metal anode becomes positively charged, while the electrolytic solution becomes negatively charged. This creates an electric field, which causes an exchange of ions between the two electrodes. The ions, which are positively charged, are attracted to the negatively charged electrode and travel through the electrolyte between the two electrodes. This movement of ions results in the storage of electric charge within the capacitor.The electric charge stored within the aluminum electrolytic capacitor can then be used for a variety of applications, such as providing power to electronic devices and protecting circuits from damages caused by voltage spikes. Additionally, these capacitors can be used to filter circuits from unwanted frequencies, as well as for high-frequency applications such as pulse signals.

Conclusion

The UUJ2E470MRQ1MS series of aluminum electrolytic capacitors is a reliable component designed for various automotive and consumer electronic applications. These capacitors are capable of withstanding temperature ranges of −40 to 105°C, and they also have a long life expectancy of up to 10,000 cycles. In addition to this, the working principle of these capacitors is based on the movement of ions between the anode and the electrolyte, allowing them to store electrical charge for a variety of electronic applications.
