Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are widely used in electronic systems due to their large capacitance, low leakage current, low cost and wide application range. The USV0J101MFD is one of the most popular aluminum electrolytic capacitors which is used in many electronic devices. This article will provide an overview of the USV0J101MFD application field and working principle.

Application Fields of USV0J101MFD

The USV0J101MFD is suitable for applications requiring high capacitance and low equivalent series resistance. These capacitors are produced in surface-mount packages, ideal for applications that require high miniaturization and low vibration/shock resistance. Such applications include power supplies, automotive electronics, robotic systems, and consumer electronics. The USV0J101MFD is a desirable alternative for applications traditionally implemented with tantalum capacitors due to its small size, greater capacitance stability over time and reverse voltage, and longer life.

Working Principle of USV0J101MFD

Aluminum electrolytic capacitors are made from two laminates of aluminum foil that are separated by a paper spacer though which electrolyte is applied. This construction is referred to as the dielectric body, and an outer sleeve of epoxy-phenolic composite is placed around the dielectric body to protect and provide insulation. An oversized anode connection is also placed on the positive side of the capacitor and connects the anode terminal to the outer sleeve.

The USV0J101MFD is a type of capacitor with a capacitance range between 8uF and 22uF and an operating voltage range between 4V and 50V. This type of capacitor has higher capacitance and lower equivalent series resistance (ESR) values than standard electrolytic capacitors, resulting in improved system performance. The key feature of the USV0J101MFD is its low leakage current which ensures high efficiency in non-interrupted power supply systems.

In operation, when the capacitor is charged to its rated voltage a reverse voltage is established, allowing current to travel through the dielectric body. This current causes a chemical reaction between the electrolyte and aluminum foil, forming a thin layer of oxide on the surface of the aluminum foil. As the charge increases, more oxide is formed and the oxide thickness increases, resulting in the establishment of a dielectric layer that inhibits current flow and stores energy.

In summary, the USV0J101MFD is a type of aluminum electrolytic capacitor that has a wide range of applications due to its high capacitance, low equivalent series resistance, and low leakage current. It can be used in power supplies, automotive electronics, robotic systems, and consumer electronics. It works through the formation of a dielectric layer, in which a chemical reaction between the electrolyte and the aluminum foil forms oxide on the surface of the aluminum foil to create the dielectric layer.
