Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitors, which are non-polarized capacitors with an etched pattern on the anode and cathode. They are one of the most widely used types of capacitors due to their low profile, high capacity, and low equivalent series resistance (ESR).

199D156X0020D6B1E3 Application Field

The 199D156X0020D6B1E3 capacitor is a common type used in consumer electronics, such as personal computers, mobile phones, video game consoles, television sets, and digital audio players. It is also widely used in telecommunications, medical equipment, automotive electronics, military electronics, and aerospace applications.

Working Principle

Tantalum capacitors are based on a technology known as surface-mount, which uses an anode and oxide film coated onto a substrate (base) material. To create electrical connections, electrodes are attached to the anode and cathode, allowing a controlled electric current to pass between them. During the electrical process, an electrochemical reaction takes place, which forms an insulating oxide layer that increases the capacitance.

When current passes through the capacitor in one direction, the formed oxide layer acts as a dielectric and stores energy in the form of electrical charge. When current passes in the opposite direction, the oxide layer collapses and the charge is released, allowing electricity to pass. This phenomenon is known as capacitive coupling, and it is extremely important in modern electronic designs.

Conclusion

Tantalum capacitors have become one of the most popular types of electrolytic capacitors due to their small size, high capacitance, and low equivalent series resistance. The 199D156X0020D6B1E3 capacitor is particularly common in consumer electronics, telecommunications, medical equipment, automotive electronics, military electronics, and aerospace applications. Its working principle relies on capacitive coupling, a process in which an oxide film forms an insulating layer when current is applied in one direction, and collapses when current is applied in the opposite direction.
