Tantalum Capacitors

Tantalum capacitors are electronic components used to store energy in an electrical field. They are used to filter, shunt, or decouple signals on a printed circuit board (PCB). Tantalum capacitors consist of a small ceramic case filled with a paste of conductive capacitive material, and two metal plates connected to the ends of the case. The metal plates are usually made of tantalum, an element which can be easily welded and has good conductivity, or other conductive alloys.

Types of Tantalum Capacitors

Tantalum capacitors come in a wide variety of types and sizes, including axial, radial, and surface-mount styles. Axial capacitors are the most common and have two leads extending from either side of the case that can be soldered to a PCB. Radial capacitors, on the other hand, have only one lead extending from the bottom, and are designed for use in compact applications. Surface-mount capacitors have no leads and are designed to be soldered directly onto a PCB. They are typically smaller and easier to install than the other types.

199D226X0025D2B1E3 Application Field and Working Principle

The 199D226X0025D2B1E3 tantalum capacitor is an axial capacitor with a very small profile. It has leads extending from either side of the case with a width of 0.25in (6.35mm). It is primarily used for bypassing, filtering, or decoupling purposes. The capacitance of the 199D226X0025D2B1E3 can be tailored to meet specific application requirements.

Tantalum capacitors store energy as an electrical field that is created between two metal plates with a conductive capacitive material separating them. This is known as a dielectric. The capacitance is determined by the size of the plates and the type of dielectric used. The leads of the capacitor are connected to the plates, and when a voltage is applied, an electrical current is created between the two plates, which is then stored as an electrostatic field.

Tantalum capacitors are designed to be robust and can handle high temperatures and vibration without degradation. Additionally, they are very compact with high capacitance values, making them ideal for use in a variety of applications, such as power supplies, DC-DC converters, and signal conditioning.
