NLW20-100 Aluminum Electrolytic Capacitors are a type of capacitors designed for relatively small values of capacitance. These capacitors are made from aluminum foil and have a dielectric layer of electrolyte, usually lithium or potassium hydroxide, between the foil layers. Their construction and working principle are similar to other types of electrolytic capacitors.

The aluminum foil used in aluminum electrolytic capacitors helps provide a high capacitance per volume. This allows them to be used in a wide range of applications, from bypassing RF currents to bypassing the surge current in a surge protector. The electrolyte dielectric layer is also used to improve the voltage and capacitance rating of the capacitor.

The working principle of NLW20-100 aluminum electrolytic capacitors is based on Faraday’s law of electrolysis. This law states that when an electrical current is passed through an electrolytic solution, a chemical reaction occurs. The reaction produces an ionic species that forms a layer on the electrode. This reaction produces a very high capacitance for the capacitor, which is why aluminum electrolytic capacitors are able to store such high amounts of energy.

The aluminum foil of the capacitor is etched so that it has a large number of small pores in the dielectric layer. These pores allow for ions in the electrolyte to move during the charge and discharge cycle. When the capacitor is charged, positive ions migrate from the positive lead to the negative lead, and the capacitor stores a charge. When the capacitor is discharged, the negative ions move from the negative lead to the positive lead, and the capacitor discharges. The current flowing through the electrolyte appears as a drop in voltage on the capacitor’s leads.

NLW20-100 aluminum electrolytic capacitors are widely used in applications such as regulating AC and DC circuits, decoupling, noise suppression, and power smoothing. They are also commonly used in switched-mode power supplies and TV sets. They are extremely reliable, and their low cost and high capacitance make them an ideal choice for many types of circuits.

In summary, NLW20-100 aluminum electrolytic capacitors are a type of capacitor designed for relatively small values of capacitance. They are constructed from aluminum foil and use a dielectric layer of electrolyte between the foil layers. The electrolyte allows for ions in the electrolyte to move during the charge and discharge cycle, allowing the capacitor to store and release energy. They are widely used in a variety of applications and are extremely reliable, making them an ideal choice for many types of circuits.
