UVZ1J470MED1TA Datasheet/PDFAluminum electrolytic capacitors are polarized capacitors with an anode constructed from a pure aluminum foil with an etched surface. The anode is covered with an insulating oxide layer which acts as a dielectric and separates it from an electrolyte layer of liquid or paste. The remaining components of the capacitor are constructed of a highly conductive material, usually a metal or carbon-film.
The UVZ1J470MED1TA aluminum electrolytic capacitor is designed for a wide range of applications in electrical and electronic equipment. It is particularly well suited for high frequency switching applications, power supply filters, audio equipment, and light emitting diode (LED) drivers. It offers low equivalent series resistance (ESR), high frequency characteristics, and long-term stability.
The working principle of the UVZ1J470MED1TA aluminum electrolytic capacitor is based on the electrical properties of the aluminum oxide dielectric layer. This is a polarized capacitor, meaning that it has an anode and a cathode and current flows in one direction only. As the capacitor is charged, a thin conducting layer of aluminum oxide is formed between the anode and the electrolyte, providing the desired electrical field between the two electrodes. This field provides the insulation between the two sockets of the capacitor.
The UVZ1J470MED1TA capacitor features a low equivalent series resistance (ESR), allowing it to handle high currents and frequencies, and providing excellent thermal dissipation. The low ESR also means the capacitor can be used in applications requiring high switching speeds, such as DC-DC converters and switching regulators. Additionally, the aluminum electrolytic capacitor is also capable of withstanding high temperatures and vibrations, making it ideal for harsh environments.
The UVZ1J470MED1TA aluminum electrolytic capacitor is a versatile device that can be used for a variety of applications. It offers superior electrical and mechanical characteristics, making it suitable for all types of power electronics applications. It is particularly useful in applications where high frequency switching is required, such as power supplies, light emitting diode (LED) drivers, and audio equipment.
