Aluminum electrolytic capacitors are among the most common types of capacitors available on the market. These capacitors provide a versatile, reliable way to store electricity and are used in many applications, such as power supplies and filters. The 381EL122M200K052 is a specific type of aluminum electrolytic capacitor with particular use cases and a unique working principle. Both the application fields and working principle of this type of capacitor will be discussed in this article.

The 381EL122M200K052 capacitor has a maximum working voltage of 200 volts and maximum capacitance of 0.22 farads. Its dimensions are 6.2 millimeters in diameter and 15 millimeters in length. It is a non-polar capacitor, meaning that it doesn\'t have a positive or negative terminal, and its polarity can be reversed. This makes the 381EL122M200K052 a versatile choice for many electronics projects. It can be used in alternating current (AC) circuits, low-voltage DC circuits, and driving motors. It is also suitable for use as a coupling capacitor for signal filtering and is often used to reduce interference in applications such as audio systems and TVs.

The working principle of the 381EL122M200K052 is similar to that of other aluminum electrolytic capacitors. It has two aluminum foils, either of which is an anode and the other a cathode. These foils are separated by an absorbent paper soaked with an electrolyte. When a voltage is applied across the two terminals, a current begins to flow, causing ions to cross the insulating separator. The positive ions are attracted to the negative terminal, and the negative ions are attracted to the positive terminal, creating a buildup of charge on each side. This creates a potential difference or "capacitance" between the two terminals.

To increase the capacitance of the capacitor, the anode and the cathode are coated with an oxide layer. This makes it easier for the ions to traverse the separator, and improves the electrical performance of the capacitor. The oxide coating also increases the voltage capability of the capacitor, which can range from 3 to 200 volts for the 381EL122M200K052. As a result, it can be used for a variety of applications, from DC to AC circuits.

The 381EL122M200K052 aluminum electrolytic capacitor is an excellent choice for a wide variety of applications, thanks to its increased capacitance, voltage capability, and non-polar design. It has a maximum capacitance of 0.22 farads, allowing it to store a significant amount of electrical charge. Its maximum working voltage of 200 volts enables it to be used in both AC and DC circuits. The 381EL122M200K052 is widely used in audio systems, TVs, power supplies, and filters, among other applications. Its working principle relies on an oxide coating to increase the capacitance, as well as two aluminum foils that are separated by an absorbent paper and an electrolyte.
