ALS81C912QH350

Aluminum electrolytic capacitors have many important features, such as high capacitance to volume ratio, low series inductance, long life, and high temperature operation. They are widely used in a variety of fields, such as power supplies, cars, motors, audio equipment, and telecommunication systems. The ALS81C912QH350 is one of the most important aluminum electrolytic capacitors today. This article will provide a brief introduction to the application fields and working principle of this capacitor.

Application Fields

The ALS81C912QH350 aluminum electrolytic capacitor is a medium-sized capacitor, with a relatively large capacity and low leakage current. Its main application fields are in power supplies and telecommunication systems. It is used in a wide range of power supply applications, such as rectifier circuits, DC-DC converters, switch-mode power supplies, AC-DC converters, and inverter circuits. In telecommunication systems, it is mainly used as a filter in communication lines. It can also be used in other electronic equipment, such as computers, TVs, and audio devices.

Working Principle

The ALS81C912QH350 aluminum electrolytic capacitor functions by storing electrical charge between two metal plates which are separated by an insulating material. These metal plates act as the two electrodes of the capacitor. The insulating material is usually an oxide film, which is formed on the surface of the metal plates. The electrodes are then connected to a source of electrical charge. When an electrical charge is applied to the electrodes, a small electric field is formed between them. This electric field stores the charge. When the electric field is removed, the charge is also released.

The ALS81C912QH350 aluminum electrolytic capacitor is a polarized capacitor, which means that one of the two electrodes has to be connected to a positive electrical source and the other to a negative source. If the capacitor is connected in the wrong orientation, this could damage the capacitor and other components on the circuit board. For this reason, it is important to ensure that the correct polarity is used when connecting this capacitor to a power supply.

Conclusion

The ALS81C912QH350 aluminum electrolytic capacitor is a reliable and efficient component, which is widely used in many different fields. Its main application fields are in power supplies and telecommunication systems, though it can also be used in other electronic equipment. It functions by storing electrical charge between two metal electrodes which are separated by an insulating material. It is important to ensure that the correct polarity is used when connecting this capacitor to a power supply.
