Introduction
Aluminum electrolytic capacitors are one of the most common type of capacitor used in electrical and electronic applications. They provide great value for their cost, size and ease of use. One type of aluminum electrolytic capacitor, the UVR2A470MPD1TD, is a radial, leaded, surface mount type capacitor. This type of capacitor is designed specifically for applications where space is limited, but reliability and performance are still important considerations. In this article, we will be discussing the application fields and working principle of the UVR2A470MPD1TD aluminum electrolytic capacitor.
Application Fields
The UVR2A470MPD1TD aluminum electrolytic capacitor is primarily used in high-frequency, high-current, low-voltage power supply applications. Such applications include DC-DC and inverter converters, many applications in the automotive industry, frequency converters, power supplies, data acquisition systems, aviation, aerospace, radio transmitters, and many other areas where a high level of electrical efficiency and reliability is needed. This capacitor is also well-suited for use in general power electronics, medical equipment, and other high-sensitivity applications.
Working Principle
The UVR2A470MPD1TD aluminum electrolytic capacitor is constructed with a positive and negative foil, which are separated by a thin, impregnated paper. The metal foil is then filled with an electrolyte paste and electrically connected to the metal contacts at the capacitor\'s terminals. The capacitor\'s internal surface is then covered with an anodized coating. This anodized covering acts as an electrical insulating layer, preventing current flow between the metal foils while also preventing electrolyte leakage.When a voltage is applied to the capacitor\'s terminals, a current passes through it, allowing electrons to flow from one plate to the other. This causes the positive plate within the capacitor to accumulate negative charges, while the negative plate accumulates positive charges. The accumulation of charges creates an electric field within the capacitor, causing a potential difference between the two plates. The potential difference is the voltage that the capacitor is capable of storing.The capacitor\'s ability to store charge is measured by its capacitance. The amount of charge a capacitor can hold is dependent on its size, surface area, and plate spacing. The UVR2A470MPD1TD has a capacitance of 10 µF and an operational temperature range of -10°C to +85°C. This allows it to handle large current loads while still operating in a viable temperature range.
Conclusion
The UVR2A470MPD1TD aluminum electrolytic capacitor is a very versatile type of capacitor and can be used in various high-current, low-voltage power supply applications. It has a capacitance of 10 µF and can handle large current loads while also operating within an acceptable temperature range. This capacitor is well-suited for use in general power electronics, automotive, medical equipment, and other high-sensitivity applications. Its compact design makes it an excellent choice for applications where space is a consideration.
