Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are a type of capacitor that uses an aluminum oxide layer as its dielectric material. They are one of the most commonly used capacitors in electronics and consist of two plates of aluminum foil separated by an oxide film. The oxide film gives the capacitor its main characteristics, namely its exceptional high capacitance-to-volume ratio, wide range of temperature stability, and low cost.

What is UBW1J470MPD1TD?

UBW1J470MPD1TD is an aluminum electrolytic capacitor manufactured by Suzhou United Electronic Co., Ltd., which is a well-known manufacturer of capacitors. The UBW1J470MPD1TD is a radial leaded capacitor, which means that it has two lead wires coming from each side of the aluminum foil plates and exit outward from the capacitor body. The capacitor body is made of aluminum, which gives it its unique shape.

Application Fields of UBW1J470MPD1TD

The UBW1J470MPD1TD is mainly used in the fields of power and high voltage. The capacitor has a voltage rating of 500V and a capacitance of 470μF. This makes it ideal for applications such as power supplies, DC/DC converters, switch mode circuits, high voltage plasma displays and electroluminescent displays. It is also suited for applications that require wide temperature ranges and stable performance.

Working Principle of UBW1J470MPD1TD

The working principle of UBW1J470MPD1TD, just like any other aluminum electrolytic capacitor, is based on the principle of electrostatic induction. When a voltage is applied across the capacitor, the electric field created between the two plates induces an electrical charge in the form of ions on the surface of the dielectric material. This creates an electric double layer where one is a positive charge and the other is negative.The electric double layer then creates a thin layer of charge, which is then responsible for the storage of energy in the capacitor. When the applied voltage across the capacitor is changed, the charge stored in the capacitor is adjusted accordingly. This process allows the capacitor to store energy and release it when needed.

Conclusion

The UBW1J470MPD1TD aluminum electrolytic capacitor is an ideal choice for applications requiring a high capacitance-to-volume ratio, wide temperature range and stable performance. Its wide application fields include power supplies, DC/DC converters, switch mode circuits and high voltage plasma displays. At the same time, its working principle is based on the principle of electrostatic induction where the electric field created between the two plates induces an electric charge in the form of ions on the oxide dielectric material, thus creating an electric double layer responsible for the storage of energy in the capacitor.
