Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits. It is distinguished by its reliable volumetric efficiency and resistance to corrosion. As with other electrolytic capacitors, tantalum capacitors are polarized, and require careful handling to prevent damage or short-circuiting.

The T491V157K010AT4280 is a flexible tantalum capacitor that is designed for use in applications such as medical and safety equipment, automotive assemblies and consumer electronics.

Working Principle

Tantalum capacitors, like other electrolytic capacitors, are constructed with two metal plates separated by a dielectric material, usually tantalum pentoxide. Electrolyte, usually a solution of potassium or sodium hydroxide, is used to bridge the gap between the two plates. The metal plates are electrically charged, with one plate becoming positively charged and the other becoming negatively charged.

When current is applied to one plate of the capacitor, it becomes positively charged and the other plate becomes negatively charged. This causes an electric field to develop between the two plates, attracting and trapping electrons on the surface of the negatively charged plate. As the charge builds, the two plates are held apart, and the magnitude of the charge and thus the electric field, remain constant.

The T491V157K010AT4280\'s electrodes are designed to optimize performance in high operating temperatures, while its insulator and electrolyte are designed to resist corrosion and provide excellent stability. The capacitor can be used in assemblies with high vibration and other mechanical stresses without decreasing its performance or life expectancy.
