Tantalum capacitors are a type of electrolytic capacitor. They are constructed with two electrodes, an anode and a cathode, made of tantalum metal, as well as a dielectric oxide layer on its surface. The electrodes are connected to a metal housing filled with an electrolyte, generally a mixture of sulfuric and phosphoric acid.

Model 199D274X9035A1V1E3 tantalum capacitors consist of a lumped type anode and cathode, an electrolyte, and a dielectric oxide layer. The anode material is typically made of a tantalum metal powder mixture with additives such as iron oxide, manganese oxide, aluminum oxide, and other materials. The cathode material can vary depending on the application of the capacitor and usually consists of an epoxy or rubber coating on the tantalum powder.

This type of tantalum capacitor is highly valued by designers and engineers for its ability to provide ultra-low leakage current and extremely high reliability in a wide range of applications. Their robustness and durability make them ideal for use in harsh environments. The low voltage drop-off potential of the dielectric oxide layer also makes them ideal for providing low ESR in DC power applications.

In terms of applications, model 199D274X9035A1V1E3 tantalum capacitors are ideally suited for high-reliability applications in industrial, military/aerospace, automotive, and telecommunication applications. These devices can be used as part of a power supply circuit to provide a steady voltage to an electronic component or as part of an AC line filter to reduce noise. They can also be used in high-current circuits such as motor drives, current limiters, and high-voltage switch-mode power supplies. As they are constructed with a dielectric oxide layer, they are ideal for use in high-sensitivity circuits, providing enhanced shielding and low leakage current.

The working principle of a tantalum capacitor is based on two main principles. The first is the electrolytic process, which involves the electrical current flowing through the electrolyte in the capacitor, which in turn creates a charge on the dielectric oxide layer. The second principle is the electrostatic process, which describes the fact that the dielectric oxide layer is insulated from the charge carriers, resulting in a stored electrical charge.

The stored charge in a tantalum capacitor is determined by the capacitance value of the device. The capacitance value is a function of the applied voltage, which is limited by the capability of the dielectric. Higher values of capacitance can be achieved by increasing the voltage, but this has a corresponding decrease the reliability of the device. For this reason, most tantalum capacitors are designed with a working voltage between 10V and 25V.

Model 199D274X9035A1V1E3 tantalum capacitors are an excellent choice for a wide range of applications. Their low ESR, ultra-low leakage current, and high reliability make them an ideal choice for a variety of applications in industrial, automotive, military/aerospace, and telecommunication applications. The working principle of a tantalum capacitor is based on the combination of a conductive anode and an electrolyte, together with a dielectric oxide layer providing electrostatic insulation from the charge carriers.
