Aluminum electrolytic capacitors are an important electronic component. The UUG2D680MNQ6MS is an aluminum electrolytic capacitor with a snap-in mounting style. It has many uses in different applications, and it can be used alone or in combination with other types of electronic components. The working principle of UUG2D680MNQ6MS is based on capacitance created by a combination of an aluminum foil and a greased paper dielectric. This article will explain the application fields and working principle of UUG2D680MNQ6MS.

Application fields

UUG2D680MNQ6MS is mainly used in high-frequency circuits and pulse circuits due to its high capacitance value, small size and high voltage capabilities. It is also used in high-frequency switching power supplies, dc/dc converters, PFC circuits, and motor drives. Furthermore, UUG2D680MNQ6MS can be used as a low frequency energy storage device for specialty applications such as regenerative braking in automotive electric systems.

Working Principle

As previously mentioned, the UUG2D680MNQ6MS utilizes an aluminum capacitor that is created by combining an aluminum foil and a greased paper dielectric. When a voltage is applied to the two plates, electrons flow out of the aluminum and form a conductor plate. This in turn creates a capacitance. The capacitance is proportional to the surface area of the aluminum plate and the distance between the two plates.

The UUG2D680MNQ6MS also uses a snap-in mounting style, which consists of an insulating plastic sleeve or tinsel wire between the external electrodes and ground connection, providing electrical insulation so that the capacitor cannot accidentally oscillate or be affected by external fields. This feature also maximizes the usability of the device over the long-term, allowing it to remain stable and reliable in the application.

Additionally, the UUG2D680MNQ6MS utilizes a self-healing feature, which allows the capacitor to repair itself in the event of damage. This is done through a process known as shoulder breakdown. Shoulder breakdown occurs when the dielectric material is exposed to too much current, which causes the aluminum foil to expand and break off. This breaks the path of current and releases energy, which reforms the aluminum oxide. This self-healing phenomenon allows the capacitor to remain functional and extends its lifetime.

Conclusion

In conclusion, the UUG2D680MNQ6MS is an aluminum electrolytic capacitor with a snap-in mounting style. It is mainly used in high-frequency circuits and pulse circuits due to its high capacitor value, small size, and high voltage capabilities. Its working principles are based on capacitance created by a combination of an aluminum foil and a greased paper dielectric. It utilizes a snap-in mounting style and a self-healing feature, which allows the capacitor to repair itself in the event of damage. This makes it a reliable and robust capacitor.
