Tantalum capacitors are type of electrolytic capacitor and have wide application in electronic products. One of them is 199D105X0025A6V1E3.

This capacitor is a polarized Tantalum capacitor with a maximum capacitance of 105μF and voltage rating of 6.3V being enclosed in an E3, or single-ended, case size with a diameter of 2.5mm and a specified height of 3.2mm. It also has a very low ESR of 25mΩ = 0.025Ω.

Tantalum capacitors are based on the principle of a chemical reaction which allows a dielectric material to form between two plates, resulting in highly efficient capacitors. By applying an electric field, an anodic oxide film is formed between the positive and negative plates of a Tantalum capacitor. This film offers high dielectric strength and stability as well as a very low leakage current, making them particularly desirable for high-reliability applications.

Though this kind of capacitor is ideal for low voltage applications when high capacitance is needed, however, he drawback is that it can be damaged easily when it is exposed to high temperatures and reverse voltages due to the chemical reaction.

The 199D105X0025A6V1E3 capacitor is designed for use in switching mode power supplies and as DC blocking capacitors in high-frequency SMPSs (switched-mode power supplies) where a low ESR, long life and high performance is required. It is also suitable for portable devices like cell phones, tablets and laptops, as well as industrial and automotive applications due to its low leakage current and low ESR. This capacitor can also be used in filtering, timer, oscillator, level shifting and voltage measuring circuits. Its small size makes it well suited for applications where board space is limited.

In conclusion, the 199D105X0025A6V1E3 is a type of polarized Tantalum capacitor with advantages such as a high capacitance, low ESR, high reliable and small size. It is primarily used in high-frequency switched-mode power supplies, portable devices and filtering circuits where low leakage and high performance is desired. Therefore, this capacitor is an optimal solution for many industrial, automotive and consumer product applications.
