Aluminum electrolytic capacitors are one of the most common types of capacitors and are used in a wide variety of electronic applications. The KMQ400VS471M35X35T2 is an aluminum electrolytic capacitor and this article will discuss its application field and working principle.Aluminum electrolytic capacitors are characterized by their large capacitance in a small package and, as such, are commonly used in power supplies to store energy. They are also used in high-frequency filter circuits, where the combination of their high capacitance and low ESR (Equivalent Series Resistance) provides good high frequency performance. Additionally, they have good self-resonant frequencies and a wide range of capacitance values. These features, along with their relatively low cost, make aluminum electrolytic capacitors a popular choice for many electronic applications.The KMQ400VS471M35X35T2 aluminum electrolytic capacitor has a capacitance of 470 μF and a rated voltage of 400V. This makes it suitable for use in high voltage applications, such as power electronics, power amplifiers, and DC-DC converters. Additionally, the large capacitance and low ESR make it an ideal choice for high frequency filters and resonant circuits. The KMQ400VS471M35X35T2 also has a wide temperature rating of -55°C to +105°C, which makes it suitable for use in extreme environments.The working principle of an aluminum electrolytic capacitor is based on the use of a liquid electrolyte as one of its electrode plates. The electrolyte, which is a combination of aluminum oxide and water, is sandwiched between two layers of aluminum foil. When a voltage is applied across the capacitor, the aluminum oxide layers break down and release oxygen, which forms an oxide film on the inner surfaces of the aluminum foils. This oxide layer acts as a dielectric between the two electrodes, creating a capacitor with a very high capacitance.The KMQ400VS471M35X35T2 is an electrolytic capacitor with a voltage rating of 400V, a capacitance of 470 μF, and an ESR of 1.2 Ohms. This makes it an ideal choice for applications requiring high capacitance, low ESR, and high voltage. Its wide temperature rating also makes it suitable for use in extreme environments. This makes the KMQ400VS471M35X35T2 a reliable, cost-effective solution for applications requiring a large capacitance in a small package.
