Tantalum capacitors are an important passive component used in many electrical and electronic assemblies. They are used in power supplies, battery backup systems, consumer electronics, and other applications that require reliable storing and releasing of electrical energy. The 199D475X0010A2B1 is a classic example of a tantalum capacitor. It is often used in large scale systems that require a low inrush current such as a switching power supply. Let’s take a closer look at this type of capacitor, the application fields and its working principle.

Specifications

The 199D475X0010A2B1 capacitor is a solid-state device that consists of two anodized tantalum electrodes, a metallic layer of manganese dioxide, and a tiny plastic film separator. It has an effective capacitance of 10 μF at 10 kHz, an operating temperature range of -55°C to +125°C, and a voltage rating of 4.75 volts. The device also has a high ESR, or equivalent series resistance, at 20 mΩ.

Application Fields

Tantalum capacitors are used in a wide range of applications, but the 199D475X0010A2B1 in particular is most often employed in low voltage circuits such as: automobile, avionics, and medical equipment, to name a few. It is also used in battery management systems and power converters, due to its low ESR, which helps reduce the impact of circuit noise and ripple voltage.

Additionally, the 199D475X0010A2B1 can be utilized in any circuit that requires reliable timing and discharge of energy. It is particularly suitable for applications where quick charging/discharging, long life, and high capacitance are required. Here it is used for energy storage, in power supplies and noise suppression.

Working Principle

The 199D475X0010A2B1 capacitor works by storing electrical energy within the manganese dioxide layer. This layer then releases energy when needed, in a process known as dielectric absorption and release. This is a very reliable process, since the manganese dioxide layer can withstand high temperatures and is not prone to leakage. The amount of energy that can be stored depends on the size and number of tantalum electrodes, and the distance between them.

The 199D475X0010A2B1 capacitor also features an ESR rating of 20 mΩ, which ensures that a low DC current and ripple voltage pass through the capacitor, while still allowing a quick discharge of energy. This is important in sensitive applications, as it reduces the risk of high-frequency parasitic oscillations and increases the device\'s overall reliability.

Conclusion

In conclusion, the 199D475X0010A2B1 tantalum capacitor is a reliable, long lasting device that can be used in a variety of applications. It has a low inrush current and ESR rating that make it especially suitable for low voltage systems, and its dielectric absorption and release process ensures a quick and safe discharge of electrical energy. All of these factors make the 199D475X0010A2B1 a popular choice for a range of applications.
