Tantalum - Polymer Capacitors

T550B107M010AT4251 is a type of through-hole or radial-leaded tantalum – polymer capacitor. Capacitors are two-terminal electrical components that can store energy and these capacitors are widely used for many applications due to their high capacitance, excellent frequency characteristics and low series resistance.

Application Field

T550B107M010AT4251 capacitors, like most capacitors, are commonly used in power supplies, coupling and decoupling, signal filtering and signal integration. It is suitable for use in DC-DC switching converter applications, where it acts as an input or output capacitor in a buck, boost or buck booster topology, allowing designers to achieve the desired requirements while meeting their size and performance targets.

The capacitor is also suitable for use in many other applications such as industrial and automotive electronics, home appliances, and LED/LCD TVs. Thanks to its high capacitance and excellent frequency characteristics, this type of capacitor is highly suitable for use in high-frequency and high-speed switching power supplies.

Working Principle

Tantalum capacitors store energy and provide a smoothing effect. They hold charge in a dielectric layer and the capacitance of this type of capacitor is determined by the surface area of the two poles, plate and dielectric, the plate material and the dielectric material between the two plates.

The plates are usually made of tantalum or aluminum and the dielectric is usually a solid polymer or film. When an electric potential is applied across the two plates, it induces an electric field between them. This charges the plate and produces an electrostatic field that displaces the polarized particles within the polymer dielectric material, thus creating a capacitance between the two plates.

The capacitance of a tantalum capacitor can range from 1nF to 1uF depending on the size of the plates and the dielectric material. The dielectric material typically used with this type of capacitor is a polymer material that allows the capacitor to operate safely at higher voltages and higher temperatures.

Tantalum – polymer capacitors have a wide range of use cases, as they offer a high level of performance and reliability in even the most demanding applications. Their ability to store energy make them ideal for use in power supplies, signal integration and filtering, and coupling and decoupling applications. With their low series resistance, excellent frequency characteristics, and high capacitance, they are an ideal choice for many types of applications.
