This article offers a better understanding of the ALS80H514QS040 and its application field and working principle.

ALS80H514QS040 Description

The ALS80H514QS040 is a radial leaded, snap-in mounting electrolytic capacitor with a voltage rating of 450 volts. It has a capacitance of 2200μF with a tolerance of ±20%. This capacitor has a limited life of 2,000 hours at an operating temperature of 85°C.

It is a non-polarized capacitor meaning that it can be connected to either polarity with no issue. Its small size and low impedance make it suitable for a variety of applications such as power supplies, audio circuits and signal conditioning.

Application Fields

The ALS80H514QS040 is used in many applications and can be utilized in different types of circuit designs. In power supplies, it is used to maintain a steady current, filter out noise and transients, and protect other components from voltage and current fluctuations.

The ALS80H514QS040 is also used in motor controllers, transformers, and inverters to reduce noise and ripples in circuits. In audio circuits, It is used to eliminate DC biases and generate smoother high frequency responses. The capacitor is also used in RF amplifiers and filters, and for signal conditioning.

Working Principle

Aluminum electrolytic capacitors are constructed with an anode made of aluminum foil, and a cathode consisting of a layer of activated, oxidized aluminum. The anode is separated from the cathode by a paper spacer. The paper spacer provides insulation and strength in the form of a dry film.

Unlike other types of capacitors, an electrolytic capacitor is polarized and must be connected in the proper orientation. When voltage is applied to the capacitor, a reversible electrochemical reaction takes place. The anode dissolves into the electrolyte solution, while the cathode is oxidized and forms a metal-oxide-semiconductor (MOS) structure.

As charge accumulates in the MOS structure, a thin oxide layer forms over the anode. This layer, known as the electric double layer, acts as a dielectric and creates the capacitance of the capacitor. As the potential of the anode is increased beyond the dielectric strength of the layer, the electrolyte breaks down and creates leakage paths.

Conclusion

The ALS80H514QS040 is a popular and reliable choice for a variety of applications. It provides satisfactory performance with long life in applications such as power supplies, motor controllers, audio circuits, and signal conditioning. It is easy to use, easy to install, and has a wide range of voltages and capacitances to choose from.

Understanding the working principle of the ALS80H514QS040 allows the engineer or technician to identify suitable applications and make educated decisions regarding capacitor selection. Whether you are a beginner or an expert in the field of electronics, knowing how aluminum electrolytic capacitors work is essential.
