Aluminum electrolytic capacitors, also called electrolytic capacitors, are special capacitors. Their capacitance and dielectric loss values vary with temperature, frequency and other factors, but they have a large capacitance, which is higher than other capacitors. The LP821M100E1P3 is a sub-kind of aluminum electrolytic capacitor with high voltage, small size and low leakage current.

LP821M100E1P3 is a long-life capacitor, with higher CL than ordinary capacitors and higher capacitance. It uses special conductive polymers as the electrolyte to increase the nominal capacity. In addition, capacitance can be increased or decreased depending on the voltage value and the temperature factor. It is also a radial, snap-in capacitor with small size and low DCL.

The LP821M100E1P3 application field is mainly as the bypassing of AC signals, such as high frequency inverter, various switching power supply circuits, voltage regulation modules, etc. Also, it can be used as the coupling component between the rectifier and filter circuit in the light power supply circuit. In the switching power supply, for example, the LP821M100E1P3 is used as the bypass capacitor, to prevent the fast-changing pulse voltage from entering the power supply output circuit. It is also used as the rectification circuit, to keep the voltage between two post circuits stable.

In terms of the LP821M100E1P3 working principle, it is based on the basic function of the capacitor, which is to store energy when a electric field is applied to a capacitor. This stored energy will increase as the capacitor\'s electric field increases, and the higher voltage will also increase the capacitance of the capacitor. But the capacitor is polarized in nature, since the internal electrode and the external electrode of the capacitor have different potentials, so the dielectric material between them generates the capacitance.

For this type of aluminum capacitor, surface-treated anode leads and electrolyte leads are used. When the electrolyte is injected, it leads to the formation of dielectric oxide film between the anode and the cathode. As the voltage is applied, electrical charges will accumulate in the oxide film, thus increasing the dielectric capacity. The thickness of the oxide film mainly depends on the applied voltage, temperature and frequency.

To sum up, LP821M100E1P3 is a kind of aluminum electrolytic capacitor, with higher capacitance and smaller size. It is widely used as the bypassing of AC signals, such as high frequency inverter, various switching power supply circuits, voltage regulation modules, etc. The working principle is based on the capacitor\'s ability to store energy when a electric field is applied to it. The thickness of the oxide film mainly depends on the applied voltage, temperature and frequency.
