This article will discuss the application field and working principle of the ALS71H303QP200.

Application Field

The ALS71H303QP200 aluminum electrolytic capacitor is typically used in audio, instrumentation, switching, and high-frequency circuits. Normally, it is used to couple and decouple signals, eliminate unwanted noise, filter deviations, bypass excessive signals, stabilize voltage, provide charge energy storage, etc. It is also used in many industrial applications, such as current limitation, AC and DC motor control, welding machines, solar inverters, DJ systems, and power transformers.

Working Principle

The functioning principle of an aluminum electrolytic capacitor is based on the principles of capacitance and electrolysis. It consists of two main components: an aluminum layer with etched grooves, and the electrolyte. The aluminum layer acts as a dielectric, and the electrolyte acts as an electrolyte. When the capacitor is connected to the power source, an electric current starts to flow, thus creating a charge accumulator in the electrolyte. At the same time, the charge builds up in the etched grooves of the aluminum layer, and this creates an electric field. The electric field in the capacitor further accumulates charges, and this produces the capacitance. Since the dielectric of the aluminum layer is relatively thin, the capacitance is relatively high.

Conclusion

Overall, the ALS71H303QP200 aluminum electrolytic capacitor has many applications, primarily in audio, instrumentation, switching, and high-frequency circuits. Its working principle involves the creation of an electric field in the capacitor, which is achieved through the movement of electric current and accumulation of charges. Thus, the capacitance is relatively high. Considering these attributes, the ALS71H303QP200 is an excellent choice for many applications.
