Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are a type of capacitor commonly used in electrical circuits. They are formed by two aluminum foils separated by an electrolyte, or “dielectric”. This dielectric provides the capacitance of the capacitor, which is determined by the area of the aluminum foils, the thickness and dielectric constant of the electrolyte, and the gap between the foils. The two lobes of the capacitor, known as electrodes, are charged according to the voltage applied. This, in turn, creates an electrical field between the electrodes, and provides a certain amount of capacitance in the circuit.

The UVZ2D4R7MPD1TA

The UVZ2D4R7MPD1TA is an aluminum electrolytic capacitor specifically designed for telecom applications. It has a diameter of just 0.8 mm, making it one of the smallest and most reliable components used in telecom circuits. It provides a dielectric constant of 8, and its operating temperature range is -55 °C to +125 °C. This makes the UVZ2D4R7MPD1TA perfect for use in hostile environments, like on satellites and space probes.

Application Field and Working Principle

Aluminum electrolytic capacitors are commonly used in the telecom industry, as they offer a high capacitance level and are small in size, making them perfect for use in telecom circuits. They are also used in the automobile and aerospace industries, as they can operate in extreme temperatures and environments. Though the UVZ2D4R7MPD1TA is designed specifically for telecom applications, it can be used in any of these industries.The working principle of the UVZ2D4R7MPD1TA is very simple. As voltage is applied across its two terminals, an electric field is created in the dielectric, which results in charge separation. This allows the capacitor to store a certain amount of energy, which can then be released when the voltage is removed. The capacitance of the capacitor is determined by the area of the aluminum foils, the thickness and dielectric constant of the electrolyte, and the gap between the foils.

Conclusion

The UVZ2D4R7MPD1TA is an aluminum electrolytic capacitor specifically designed for telecom applications. It is one of the smallest and most reliable components available and provides high levels of capacitance in extremely hostile environments. Its working principle is simple – as voltage is applied across its terminals, an electric field is formed, allowing the capacitor to store energy which can be released when the voltage is removed.
