LPX471M250A4P3

Aluminum electrolytic capacitors, abbreviated as Al-elcos series, are generally polarized capacitors whose anode electrolyte is an aluminum oxide film. LPX471M250A4P3 is one of these aluminum electrolytic capacitors.

LPX471M250A4P3 features a pressure-sensitive aluminum foil electrode, which enables the capacitor to have the characteristics of a large capacitance, high-voltage resistance, and low equivalent cost. It offers good heat and mechanical shock resistance. Additionally, the operating temperature of the part can range from -55 to +105 Celsius.

The typical application fields of LPX471M250A4P3 include power supply, voltage or frequency stabilization, DC-DC converter, UPS, high frequency power, and various signal filtering applications. These capacitors boast superior characteristics such as low ESR (Equivalent Series Resistance) and high ripple current. By using LPX471M250A4P3, the working life of high frequency power will be extended.

The working principle of LPX471M250A4P3 is similar to other aluminum electrolytic capacitors. The anode/negative electrode is made of sintered aluminum oxide, through which an electric current can flow freely and generate an electric polarization phenomenon owing to the electric double layers formed in the anode/negative electrode thin film surface. This leads to the generation of a voltage on the surface as well as a capacitor voltage.

Additionally, as the gas released from the inner electrode, the immersed electrolyte forms an insulation film on the surface of the inner electrode, which makes the LPX471M250A4P3 have good insulation performance, and prevents the inner electrode from short circuit. It should also be noted that, when the reverse voltage is applied to the capacitor, no current flows. This is because the reverse electric field developed on the anode casing surface reduces the electric field on the anode surface and stops the electron movement.

In conclusion, the LPX471M250A4P3 is an aluminum electrolytic capacitor excellent in performance and suitable for various applications ranging from power supply to high frequency power. Its stable and reliable performance is ensured by the electric polarization phenomenon generated by the anode/negative electrode and electrolyte.
