Aluminum electrolytic capacitors are components in electrical circuits used to store energy for short periods of time. They are polarized capacitors with an anode (positive) and a cathode (negative). They are constructed of aluminum foil with an oxide layer acting as the dielectric, electrolyte as a combination of liquid and/or solid electrodes, and a container or casing. Unpolarized capacitors have the same anode and cathode, while aluminum electrolytic capacitors have two distinct electrodes.

UUH1A471MNQ1ZD is a kind of aluminum electrolytic capacitor. It’s mainly applied in automotive electronic circuits, servers, computers, industrial electronic equipment, power supplies, LED lighting and other high current circuits. Its maximum working voltage (DC) is 100V, and its maximum rated ripple current (100kHz) is 28A.

The working principle of UUH1A471MNQ1ZD is simple. In the presence of an electric field, electric charges tend to accumulate on the dielectric layer. The electric charges accumulate on the surface of the oxide layer and form a double layer. The negative charge carriers accumulate on the oxide film on the anode side, and the positive charge carriers accumulate on the oxide film on the cathode side. The electric charges form a capacitor (positive electric field on one side and a negative electric field on the other side) and correct capacitor operation is provided.

In a UUH1A471MNQ1ZD capacitor, the basic structures include an aluminum foil anode, a thick oxide layer, a sealed electrolyte, and an aluminum foil cathode. The entire process of producing the capacitor starts with the anode collector. The aluminum foil used for UUH1A471MNQ1ZD is generally between 0.02-0.05mm thick, and it is finely etched to increase the area of the anode and cathode to increase the capacitance. The oxide layer acts as the dielectric to store electrical charge. The electrolyte is then soaked into the space between the anode and cathode. The thickness of the electrolyte liquid depends on the capacitor\'s capacitance.

The function of the electrolyte is twofold-it creates an electrochemical reaction to increase the dielectric strength and provide cooling to the capacitor when the load current is high. When the capacitor is energized, the aluminum cathode is driven into and out of the electrolyte and is permanently polarized.

UUH1A471MNQ1ZD aluminum electrolytic capacitors have a wide range of applications including power supplies and filters, audio amplifications, stabilizers, controlling circuits, circuit protection, filtering, DC-DC converters, oscillators, frequency tuning, and signal design. With their large capacitance ratings, low equivalent series resistance (ESR), and high ripple current ratings, UUH1A471MNQ1ZD capacitors are ideal for applications requiring significant power reserves and frequent current spikes.

In conclusion, UUH1A471MNQ1ZD aluminum electrolytic capacitors is a kind of component in electrical circuits, it is mainly applied in automotive electronic circuits, servers, computers, industrial electronic equipment, power supplies, LED lighting and other high current circuits. Aluminium electrolytic capacitors have the advantage of providing a large capacitance in a small package, making them ideal for a large variety of applications.
