Aluminum electrolytic capacitors are divided into power supply filter and noise filter. They are widely applied in many electronics, such as microprocessor, personal computers and its peripherals, communication equipments, medical equipments, measurement and controlling systems, etc.

The UKA1V220MDD1TD belongs to the aluminum electrolytic capacitors. To find its application fields, we should take further analysis of its parameters. The UKA1V220MDD1TD Chip aluminum electrolytic capacitor has 220μF capacity, 6.3V rated voltage, Operating temperature range is -40°C~105°C. 7mm×6.3mm×Height 4.5mm, Mounting pitch is 4.0mm. This parameter set can properly explain its application.

The UKA1V220MDD1TD Chip aluminum electrolytic capacitor can be used in multiple scenarios. Firstly, it can be used in frequency control circuits and EMC of devices. It can also be used in voltage stabilizing circuits, filtering circuits and other high-frequency circuits for power supply voltage.
In addition, low-frequency circuits of devices or systems can also be applied with these capacitors. Static battery discharge devices of vehicles, electronic clocks, electronic toys and electronic instruments are widely equipped with these capacitors. As for applications at temperature of 70 °C and lower, UKA1V220MDD1TD can be widely usedin amplifiers, audio systems, telephone systems and TV sets.

The core working principle of aluminum electrolytic capacitor is also related to its applying fields. In essence, aluminum shell acts as an anode and oxygen anion as a cathode. In use, the anion is oxidized and combined with aluminum foil in the anode, which together forms an electrostatic field with certain capacitance. In this way, a certain DC pressure will be stored through the positive and negative electrolytic layers of aluminum electrolytic capacitor.

The capacitance value of aluminum electrolytic capacitor is determined by its anode and cathode area, the distance between them and the applied voltage. When the voltage is applied, the capacitance value of electrolytic capacitor increases, and when the polarization is held at a certain reversed voltage, its capacitance will adapt to the steady value.
