Aluminum electrolytic capacitors, or simply electrolytic capacitors, have many applications as a type of energy storage passive electrical component. The UVK1V470MDD1TD is an example of such a capacitor and is characterized by a very small profile for its high capacitance rating, making it suitable for a number of applications. This article focuses on the application field and working principle of the UVK1V470MDD1TD.

The UVK1V470MDD1TD is a miniature aluminum electrolytic capacitor with a capacitance rating of 470uF and a working voltage of 1.0V. It is especially approved for use in cell phone battery protection circuits and LCD backlighting circuits. This device is a very economical choice for providing a high capacitance and low-working voltage. Additionally, it is also commonly used in DC-DC converters and switching power supplies.

The UVK1V470MDD1TD has a small size for a device with such a high capacitance rating, measuring in at 4mm in diameter, 7mm in length, and with a total height of 1.5mm. This makes it possible to mount many of these onto the same circuit board, allowing for the conservation of valuable space. The use of a metal aluminum plate makes the capacitor very resistant to shock and vibration, further improving its suitability to many applications.

The working principle of the UVK1V470MDD1TD is based on the use of a metal aluminum plate, a cathode, and a dielectric insulator, usually an electrolyte like boric acid or manganese dioxide. The metal aluminum plate and the cathode form two plates separated by the dielectric insulator, which functions as an electrical barrier. When a voltage is applied, the metal aluminum plate takes negative charges and the cathode takes positive charges. This creates a potential difference between the two plates, and charges build up on them. This creates a field of charge and stores energy.

The capacitance rating of a device like the UVK1V470MDD1TD is determined by the characteristics of the dielectric insulator and the size and spacing of the two plates. A thinner dielectric insulator or larger plate area can increase the device’s capacitance rating, while a thicker dielectric insulator or smaller plate area can decrease the capacitance. The continual charging and discharging process is used to store and release energy, allowing the device to act as an energy storage device.

In conclusion, the UVK1V470MDD1TD is a miniature aluminum electrolytic capacitor with a capacitance rating of 470uF and a working voltage of 1.0V. It is approved for use in applications such as cell phone battery protection circuits, LCD backlighting circuits, DC-DC converters, and switching power supplies. It is also very resistant to shock and vibration due to the use of a metal aluminum plate. The working principle of the device is based on the use of a metal aluminum plate, a cathode, and a dielectric insulator, which functions as an electrical barrier to create a potential difference and stored energy.
