Aluminum electrolytic capacitors are energy storage devices widely used in various areas due to their high energy density, low cost and high reliability. Among them, UPS2D470MHD1TO belongs to the category of Radial Aluminum Electrolytic Capacitor. It is characterized by long cycle life, low leakage current and quick start-up. In order to make sure the safe and stable operation of the equipment, its application fields and working principles must be well understood.

UPS2D470MHD1TO is suitable for applications that need low-capacitance and low-voltage electrolytic capacitors, such as SMPS and DC-DC converter, supply and control electronics, panel meter and other control circuits. It can also be used in high-frequency circuits for energy storage, filtering, and low leakage current. In terms of performance, its rated voltage is of 2-16V, its rated operating temperature is from -40°C up to +85°C, the capacitance range is from 0.1µF to 470µF, and its impedance is at least 2000.

The working principle of UPS2D470MHD1TO is based on the principle of electric double-layer capacitance. In the capacitor, the anode is an aluminum foil with a thin layer of oxide film, which is drilled out with a more developed technology. The cathode is a activated carbon material. The two layers are separated by a thin layer of electrolyte. The formation of electric double-layer capacitance is not a discharge and charging process, but is formed by the electrostatic attraction between the positive and negative charges on each side.

When UPS2D470MHD1TO works, the anode contacts the negative pole of the power supply and the cathode contacts the positive pole of the power supply. Under the action of the electric field, electric charges move from the anode to the cathode, and at the same time, the anode forms a thin oxide film layer, which makes the capacitor have a certain capacitance value and prevents the current from leaking. This is the basic structure and working principle of aluminum electrolytic capacitor.

In summary, UPS2D470MHD1TO is a kind of radial aluminum electrolytic capacitor with the characteristics of long cycle life, low leakage current and quick start-up, which is suitable for SMPS, DC-DC converter, supply and control electronics, panel meter, low-capacitance and low-voltage electrolytic capacitors and other applications. Its working principle is mainly based on the principle of electric double-layer capacitance, and its structure includes an anode with a thin oxide film, a cathode made of activated carbon material and a thin layer of electrolyte. Since the electric double-layer capacitance does not involve the process of discharge and charging, a certain amount of capacitance value can be achieved to prevent current from leaking.
