Tantalum capacitors are nonpolarized electronic components that use an oxide dielectric to store electrical energy between two conductive plates. They are most commonly used in circuit applications as coupling and bypass elements. The exotic oxide material used in these capacitors can achieve a capacitance value in the range of 1 μF, making them ideal for use in noise suppression, filtering, and timing circuits, as well as in high-performance audio and medical devices.

The tantalum capacitor featuring the numerical code “199D475X9025BXV1E3” is a miniature surface-mount component that is rated for a voltage of 3 V, with a capacitance of 4.7 μF. Tantalum capacitors are featured in a variety of forms to suit different application requirements. When measuring size, the nominal length is coded with a three-digit number, indicating the length in tenths of an inch. The width varies by type, but for this particular component, it is 0.75”.

The most common application of this size and capacity of tantalum capacitor is for bypassing and decoupling circuits in power supplies and audio amplifiers. The low internal series resistance (ESR) of the tantalum capacitor allows it to maintain a low impedance in the circuit as frequency rises. This helps to prevent oscillation and protect the circuit from high frequency noise. It is also used when multiple parallel capacitors are required in a certain application, because of its minimal component size.

The working principle of the tantalum capacitor is the physical phenomenon of dielectric polarization. When the conductive plates are connected to a power source, electric charges accumulate at the oxide dielectric material, causing a strong electric field to form within the oxide. This electric field counterbalances the applied voltage and creates a capacitance, allowing energy to be stored. This allows the capacitor to act as a passive component in an electrical circuit and serve as a filter or a timing component.

The tantalum capacitor featuring the numerical code “199D475X9025BXV1E3” is a versatile component that offers low series resistance and minimal size. With its 3 V rating and 4.7 μF capacitance, it is best-suited for use in noise suppression, filtering, and timing circuits, as well as in high-performance audio and medical devices. As an exotic oxide material, this tantalum capacitor demonstrates excellent capacitance retention and low self-heating under low duty cycle applications. Its dielectric material also enables it to be used for high-frequency signal signal filtering and shielding, offering reliable performance for various application fields.
