Aluminum Electrolytic Capacitors - USW1H4R7MDD1TE application field and working principle

Aluminum electrolytic capacitors, also known as aluminum electrolyte capacitors, are polarized capacitors with a very large capacitance per unit volume. It is made of anode aluminum foil with an etched surface, and the anode surface is oxidized and forms an insulating aluminum oxide film as the dielectric. A very thin paper soaked in electrolyte is used as the separator.

An aluminum electrolytic capacitor consists of an anode foil with an etched surface, a cathode electrolyte, and a separator, which is a piece of aluminum oxide dielectric film formed in situ. The anode and cathode leads of the aluminum electrolytic capacitor are connected respectively to the two sides of the anode and the cathode, and the electrolyte is applied to the construction.

Aluminum electrolytic capacitors can go through components and assemblies. USW1H4R7MDD1TE is a among these components. Its applications include high current filter circuit for switch power supply, low ripple filter circuit for power amplifier, high precision circuit for electronic clock radio, low noise filter circuit for audio and video device, and so on.

The working principle of aluminum electrolytic capacitors is mainly related to charge and discharge, the so-called “Electrolytic effect”. When the forward voltage is applied to the capacitor, the anode forms precipitated oxygen ions and the ions will migrate to the cathode, resulting in an immediate charge in the capacitor. This process is also accompanied by the ion migration of the electrolyte molecules, which charges the capacitor. When the voltage is reversed, the oxide layer of the capacitor also acts as an insulator and the capacitor is effectively discharged.

Aluminum electrolytic capacitor has the advantages of large capacitance, long life, low ESR, and wide temperature range application. The USW1H4R7MDD1TE series has high voltage, low Current leakage, stable performance, high ripple current, long life, smaller size and higher energy efficiency, making it an ideal choice for high-power filter circuits in switch power supplies, audio and video amplifiers, and electronic clocks.

In summary, USW1H4R7MDD1TE aluminum electrolytic capacitors have both strong application fields and working principles. It has wide temperature range application, stable characteristics and high ripple current, which make it the ideal choice for power filter circuits, audio and video amplifiers, and electronic clock radio circuits.
