Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used types of capacitors today due to their high capacitance, high temperature stability, and low equivalent series resistance. They are mainly used for high voltage, high power applications such as switch-mode power supplies, motor control, UPS units, and audio amplifiers. The URZ1H471MHD aluminum electrolytic capacitor is a popular choice for these applications, offering high capacitance, excellent performance, and long life.

Application Field of URZ1H471MHD

The URZ1H471MHD capacitor is a radial type aluminum electrolytic capacitor with a voltage rating of 470V, a capacitance value of 47 uF, and a ripple current of 400 mA. It is an ideal choice for high voltage, high power applications such as power supply filters, DC-DC converters, motor control, UPS units, and audio power amplifiers. The capacitor also has a wide operating temperature range of -40°C to 85°C, making it suitable for both indoor and outdoor use.

Working Principle of URZ1H471MHD

Aluminum electrolytic capacitors are based on the electrochemical principle of Faraday\'s law. An electrolyte, such as an organic solvent, is used to dissolve an anode material, such as aluminum hydroxide. The acidic electrolyte and the anode form a polarized electrolyte electrode. A second electrode (the cathode) is formed by applying a voltage across the anode. When this is done, electrons are driven from the anode to the cathode via the electrical field, thus forming a capacitor. The aluminum oxide layer that is formed between the two electrodes acts as an insulator, resulting in increased capacitance.

In the case of the URZ1H471MHD, the aluminum oxide layer is integrated with the anode material, resulting in a higher capacitance. This capacitor also features a longer lifetime due to its high temperature stability. This makes it an ideal choice for high-power applications where long-term reliability is important.

The URZ1H471MHD also features an ultra-low equivalent series resistance (ESR) and low inductance, allowing it to remain stable even in high-frequency switching applications. This makes it ideal for applications such as motor control and audio amplification.

Conclusion

The URZ1H471MHD aluminum electrolytic capacitor is a popular choice for high-power applications due to its high capacitance, high temperature stability, and low equivalent series resistance. It is ideal for applications such as power supplies, DC-DC converters, motor control, UPS units, and audio amplifiers. With its high-performance characteristics, the URZ1H471MHD is an ideal choice for a wide range of applications.
