Aluminum electrolytic capacitors are important components in many electrical and electronic equipment, although they are most widely used in voltage regulation, filtering and power electronic switching circuits. The UVZ2C330MPD1TD is an aluminum electrolytic capacitor with a nominal capacitance of 330 μF, and is part of a large family of UVZ capacitors available from Nichicon. It is a radial leaded capacitor intended for use in high voltage DC applications.

Applications

The UVZ2C330MPD1TD is a high voltage DC electrolytic capacitor suitable for applications such as power supplies and regulators, or battery chargers. They are also suitable for waveform shaping or low pass filtering applications. In particular they are designed for applications up to 2000V, which is significantly higher than most common non-electrolytic capacitors. The construction and robustness of the capacitor makes it suitable for industrial and commercial applications where protection against transient voltage spikes, motor surges or lightning is required.

Working Principle

An aluminum electrolytic capacitor works by forming a thin layer of aluminum oxide within the capacitor dielectric. The oxide layer acts as a barrier between the positive charge on the aluminum anode and the negative charge on the cathode. When a voltage is applied to the capacitor, the oxide layer will break down, allowing electrical charge to pass through. This process is known as forming or dielectric breakdown, which creates an electric field across the oxide layer.

The positive and negative charges on the two plates attract opposite polarity charges in the oxide layer, forming an electrolyte level that increases with applied voltage. This inverse voltage to current relationship is what gives the capacitor its capacitance value. The parallel combination of capacitance and resistance forms the equivalent circuit of the capacitor, which is used in a variety of circuit designs.

Conclusion

The UVZ2C330MPD1TD aluminum electrolytic capacitor is a high voltage DC device intended for use in power supplies and regulators, battery chargers, waveform shaping, or low pass filtering applications. Its high voltage rating and robust construction makes it suitable for industrial and commercial applications where protection against transient voltage spikes, motor surges or lightning is required. It works by forming a thin layer of aluminum oxide within the capacitor dielectric, which acts as a barrier between the positive charge on the aluminum anode and the negative charge on the cathode.
