Tantalum Capacitors

Tantalum capacitors are tantalum electrolytic capacitors that consist of a tantalum foil anode, dielectric oxide film, and a cathode. They can be used in a wide range of applications and offer a variety of advantages over other types of capacitors, including higher capacitance, higher peak current ratings, lower equivalent series resistance (ESR), longer shelf life, and better temperature stability. The dielectric oxide films used in tantalum capacitors are usually manganese dioxide (MnO2) or niobium pentoxide (Nb2O5).

199D685X0035D6V1 Application Field and Working Principle

The 199D685X0035D6V1 is a surface-mount tantalum capacitor that is mainly used in high-voltage, high-reliability power supply, and other circuits. It has a nominal capacitance of 6.8 µF, a rated voltage of 35 V, and an ESR of 5 ohms. It is suitable for pulse DC/DC converters, LED drivers, and audio equipment. The working principle of the 199D685X0035D6V1 is the same as that of any other type of capacitor. It works by storing and releasing electric energy through an arrangement of tantalum electrodes, which are separated by a dielectric oxide film. The capacitance of the device is determined by the surface area of the electrodes and the thickness of the oxide film. When a voltage is applied across the device, a charge current begins to flow, which builds up a charge store at the electrodes and induces an electric field in the oxide film. When the electric field reaches a certain level, the electric field forces electrons to jump across the gap, which stores energy in the form of a charge. This charge can be released when the voltage across the device falls below a certain level, which discharges the capacitor and sends the stored energy back out. This process can be repeated indefinitely, which is how the device works.

Tantalum capacitors are generally used in a variety of applications such as electric vehicles, telecommunication systems, computers, audio equipment, and medical electronics. Their advantages include long shelf lifetime, higher capacitance, lower ESR, and better temperature stability, compared to other types of capacitors. In addition, they require less space and are typically cost-effective. They can also be used in high-voltage, high-reliability, and mission-critical applications due to their high voltage and energy ratings.

In conclusion, the 199D685X0035D6V1 is a type of tantalum capacitor that is primarily used in high-voltage, high-reliability power supply and other circuits. It has a nominal capacitance of 6.8 µF and a rated voltage of 35 V. Tantalum capacitors offer a variety of advantages over other types of capacitors and are used in a variety of applications where their high voltage, energy ratings, and long shelf lifetime are greatly beneficial.
