Tantalum capacitors are a special type of capacitor that have several unique characteristics compared to traditional ceramic or aluminum electrolytic capacitors. The tantalum capacitor code "199D475X96R3A1V1" highlights several of these distinct features. This code contains information about the capacitor’s properties, field of application, and working principle.

One of the advantages of tantalum capacitors is that they are available in a wide range of sizes, voltages, dielectric types, and capacitance levels. The size and voltage designation of a tantalum capacitor are represented by the first two digits of the code, “19”. These numbers indicate that the device is a 19mm x 9mm rectangular case with an applied voltage of 6.3V or 10V.

The next two digits of the code, “9D”, describe the dielectric type. “D” stands for tantalum-oxide or polyphenylene-oxide (PPO) type dielectric materials, which are excellent for long-term reliability. The final four digits of the code indicate the dissipation factor, maximum capacitance, and other specifications of the capacitor.

The application field and working principle of a tantalum capacitor depend on its dielectric material. For tantalum-oxide dielectric capacitors, they are mainly used in power electronics, high-voltage switching circuits, and coupling/blocking applications due to their stable electrical characteristics up to high temperatures and severe environmental conditions. The working principle of these capacitors is the same as that of other capacitors: they store energy between two conductive plates separated by an insulating dielectric material.

In contrast, polyphenylene-oxide (PPO) dielectric tantalum capacitors work differently and are mainly used in signal filtering and signal coupling applications. Their electrons are dispersed over multiple electrode layers, resulting in a much smaller leakage current compared to tantalum-oxide capacitors. For signal filtering applications, the working principle of a PPO capacitor is to filter out high-frequency signals and keep the AC component out of the DC signals, thus providing stability to the circuit.

Overall, the code “199D475X96R3A1V1” describes a 19mm x 9mm rectangular tantalum capacitor with a voltage rating of 6.3V or 10V and either a tantalum-oxide or PPO dielectric material. Depending on the dielectric material, these capacitors can be used in either power electronics, high-voltage switching circuits and coupling/blocking applications, or signal filtering and signal coupling applications.
