Tantalum capacitors are a robust type of non-polarized electrolytic capacitor used in many electronics applications. They feature a higher capacitance than other types of capacitor, offer extremely high reliability, and are relatively small in size. The model number 199D685X0035D2B1E3 is a type of tantalum capacitor, and the following explains its application field and describes the underlying working principle.

Application Field

The tantalum capacitor model 199D685X0035D2B1E3 is designed primarily for electronic circuits which require high-frequency signal transmission. Its ability to achieve a maximum capacitance level of almost 6.85 μF while taking relatively little space makes it ideal for applications such as integrated circuits, power supplies, and filter circuits. In addition, this model of tantalum capacitor is able to withstand exposure to extreme temperatures, chemical, and mechanical stress – making it particularly suitable for use in automotive and avionics systems.

Working Principle

Unlike standard capacitors, tantalum capacitors provide a unique working principle in which the positive and negative electrolytes are housed inside a single cylinder. The cylinder is filled with an electrolyte paste comprised of a mixture of dissolved electrolytes and solid electrode materials, usually tungsten oxide, tantalum oxide, and anniobium oxide. When an electric current is applied to the system, the oxide\'s electric double layer causes an electron exchange between the positive and negative plates, creating a dielectric barrier. This barrier is what allows the capacitor to store energy.

The frequency at which a tantalum capacitor can operate depends on the applied electric current and the internal design of the ceramic body. In the case of the model 199D685X0035D2B1E3, the maximum ripple current has been tested at up to 35 amps and the maximum operating frequency swept over the range of 10 kHz to 500 kHz. This makes the capacitor suitable for high-frequency signal transmission applications.

Conclusion

The tantalum capacitor model 199D685X0035D2B1E3 is highly reliable and can operate in extreme environmental conditions. Its high capacitance and small size make it ideal for applications that require high-frequency signal transmission, such as integrated circuits, power supplies, and filter circuits. Furthermore, the dielectric barrier created by the ceramic body allows the capacitor to store energy, allowing it to operate at frequencies ranging from 10 kHz to 500 kHz.
