Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of polarized capacitor that uses an aluminum oxide film as the dielectric, also known as electrolyte. Generally, the anode or positive terminal is connected to the aluminum foil of the capacitor, while the other terminal, the cathode or negative plate, is connected to the oxide layer. These capacitors have very low leakage current, high capacitance, and low loss, which makes them ideal for use in applications such as high-current/high-frequency coupled circuits, motor control circuits, switching supplies, filtering, and telecommunication equipment.

The UBX1J471MHL1TN is an Aluminum Electrolytic Capacitor that consists of a capacitor element mounted on a metallic body. It has a low ESR and is typically used for high frequency circuits and electronic equipment. They are a reliable and long-life capacitor, having an extended operating temperature range from -55 to +105°C.

The UBX1J471MHL1TN has two primary application fields:

• Low ESR Requirements. The UBX1J471MHL1TN can be used when a low ESR is needed. This makes it suitable for applications that have high frequency or noise conditions, such as in television receivers, computers, telecommunications equipment, chip packages, and motor drives.
• Counter Electrode. The UBX1J471MHL1TN can be used in circuits as a counter-electrode. This is particularly useful in situations when noise immunity is desired, such as in radio receivers, audio amplifiers, and motor drives.

In addition, the UBX1J471MHL1TN\'s working principle is based on electrochemical reactions. In short, the aluminum coating of the capacitor is a type of anode and the oxide film is the cathode. When an electric current is passed through the capacitor, it causes a reaction between the aluminum coating and the oxide film, forming an ionic layer between them. This creates an insulating layer and gives the capacitor its dielectric properties.

Due to the nature of the Aluminum Electrolytic Capacitor, it is important to ensure that it is installed in the correct orientation and that the capacitor is properly matched to the application. In addition, it is also important to remember that Aluminum Electrolytic Capacitors are a polarized component, meaning that they must be connected in the correct direction in order to properly function.

In conclusion, the UBX1J471MHL1TN is an Aluminum Electrolytic Capacitor that is useful for applications with low ESR requirements or as a counter electrode. Its working principle is based on electrochemical reactions that create an insulating layer between the anode and the oxide film. While it is a reliable and long-life component, it is important to install it in the correct orientation and ensure that it is matched to the application in order to ensure proper operation.
