Aluminum electrolytic capacitors are widely used in power electronics and automotive electronics. They are essential components of electronic circuits because they store electrical energy and have the ability to discharge it. So what is the application field and working principle of UUG2D470MNQ1MS?

Application Field

The UUG2D470MNQ1MS is a type of aluminum electrolytic capacitors with stands of 2.5V-16V, which is widely used for board-level applications such as desktop power supply, server power supply, telecommunications, and household appliances. It is able to withstand some challenges with thermally hot environment and limited space.

It enjoys a few advantages such as low impedance, low equivalent series resistance (ESR) values, large ripple currents and high capacitance values per volume. Moreover, it comes with small-sized, Sn-plated, and lead-free terminations. Although it\'s useful for applications that require low ESR, its working temperature range is -25~105℃, which implies that it may not fit applicable in extreme environments.

Working Principle

An aluminum electrolytic capacitor is an electronics component composed of two aluminum foils separated by a paper separator, immersed in an electrolyte. It has a positive and a negative plate. In between, there is a paper separator soaked in electrolyte and soaked between two sheets of aluminum. One sheet of aluminum has been etched (etched) and contains extremely small holes. The electrolyte is composed of highly conductive ions.

The working principle of UUG2D470MNQ1MS aluminum electrolytic capacitor is quite simple. The positive and negative plates form an electrical circuit like a normal capacitor. When there is positive potential on the positive plate, negative potential on the negative plate and a DC current flowing, positive ions from the electrolyte will pass through the paper separator and arrive to the negative plate, then neutralize with the electrons on the plate. During this process, the capacitor stores electrical energy in form of charge.

When there is an AC current flowing, the positive and negative plates will alternate between positive and negative potentials. It will cause the capacitor to absorb and release electrical energy. Thus, the applied voltage will generate a current with low pass characteristics, which is useful for filtering.

Conclusion

The UUG2D470MNQ1MS aluminum electrolytic capacitors are mainly applicable for board-level applications and have a wide circuit operation voltage ranging from 2.5V-16V. Its working principle is to store electrical energy in form of charge using an aluminum foil, paper separator and electrolyte, and to convert the applied voltage into a current with low pass characteristics.
