Application fields of ALS71H273QW250

The ALS71H273QW250 aluminum electrolytic capacitor is mainly used in electronic control systems, communication circuits, switching power supply circuits, filter circuits, and DC/DC converter circuits. This type of capacitor is often used in high-frequency applications with temperatures ranging from -55 degrees Celsius to +105 degrees Celsius.

Aluminum electrolytic capacitors can be used in various fields from the microcontrollers and embedded processors that control the functions of complex electronic devices, to automobiles, which require a reliable electrical component. This capacitor plays a significant role in filtering noise, smoothing ripple, boosting oscillation, and charging/discharging circuits. It is also ideally suited for cases where large current capacitors are needed.

Working Principle of ALS71H273QW250

Aluminum electrolytic capacitors are shaped like a cylinder with two metallic plates placed along the external wall of the cylinder. One of the metallic plates is usually made of aluminum, while the other is constructed of a conductive carbon-based material. Inside the cylinder, an electrolyte is suspended between the two metallic plates. The positive electrode is connected to the metallic plate made of aluminum, while the negative electrode is connected to the metallic plate made of carbon.

When an electrical current passes through the cylinder, the electrons in the aluminum alloy plate enter the electrolyte with the help of current. This creates a layer of corrosion in the plate of aluminum alloy. The corrosion increases the surface area of the electrode and thus increases the charge capacity of the aluminum electrolytic capacitor.

After a certain amount of current, the charge capacity of the capacitor reaches a maximum point and the capacitor will be saturated. At this point, any extra current which passes through the capacitor can cause damage due to the increased heat generated.

Conclusion

The ALS71H273QW250 aluminum electrolytic capacitor is a versatile, reliable, and cost-effective device that is used in a variety of electrical and electronic applications. It is capable of reliably providing a range of electrical parameters and has a wide temperature range. Its working principle is based on electrolysis and corrosion of the aluminum alloy plate.
