Aluminum electrolytic capacitors are reliable, low-cost components for the regulation of power supplies such as DC to DC converters, voltage regulators and current sources. With the development of the power electronics industry, the application fields of aluminum electrolytic capacitors are continuously upgraded. The UMA1H4R7MDD1TE is one of these components, and its application field and working principle are discussed in this text.

The UMA1H4R7MDD1TE is a low-impedance aluminum electrolytic capacitor with a wide temperature range and can operate at a temperature between – 40°C to + 105°C. The characteristics of this capacitor also include /-20% voltage regulation in the range of 25-105°C, as well as excellent thermal stability. Its best characteristics are high ripple current capability and low ESR, which significantly increase its application field.

The UMA1H4R7MDD1TE can be used in the regulation of low-power power supplies used in low-power appliances such as consumer electronics and the industrial automation. By filtering out the electrical noise generated by the switching of these appliances, it can reduce the power consumption and extend the lifetime of the equipment. It can also be used as an output regulator in high-voltage circuit formulas such as in DC to DC power converters.

The working principle of the UMA1H4R7MDD1TE is based on the basic principles of electrolytic capacitors. When voltage is applied to the capacitor, an electric field is established between its two electrodes. As a result, the electrical energy stored in the capacitor is in the form of a dielectric. This stored electrical energy will also result in an electrical current when the capacitor is discharged.

The UMA1H4R7MDD1TE is constructed with a multilayer capacitor structure made up of layers of dielectric-coated aluminum and cathode foils, which are in contact with a liquid electrolyte. During operation, the electrical field created by the applied voltage diffuses through the electrolyte and forms a layer between the two foils. When the voltage is then removed from the capacitor, the electrical energy stored in the form of a dielectric is released, allowing the capacitor to discharge.

The UMA1H4R7MDD1TE is designed for use in a variety of applications from power conversion to high-performance electrical regulation. Its low ESR, superior ripple current handling capability and wide temperature range make it a suitable choice for many applications. Additionally, its high overload current capability and low power consumption make it suitable for use in low power applications. It is also highly reliable, making it a reliable component for the regulation of power systems.
