Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitors, which use a metallic tantalum anode, covered by an oxide dielectric layer, as one of the conductive plates. The other plate is made out of a porous sintered electrode which collects a liquid or gel-like electrolyte. thanks to their good performance, its use as a high-stability capacitor in electronic circuits has been extended in a wide range of applications.

173D226X5015XW application field and working principle

The 173D226X5015XW is a polymeric type of tantalum capacitor, also experience as "solid tantalum", designed to provide a higher capacitance range than other capacitor types, thanks mainly to the special polymer film used in its manufacturing. This capacitor has been designed to be used in a wide range of different capabilities, from simple as a decoupling capacitor in low voltage circuits, to more sophisticated uses as charge storage in SMD power supplies, or high-voltage low ESR voltage regulators. Its features include an operating temperature range between -55°C to +125°C, low ESR, and a long reliable lifetime.

The working principle behind the 173D226X5015XW is relatively simple. Its main components are the anode, made of a metallic tantalum mass, the dielectric ceramic layer which prevents electrical conduction between the electrodes, and the liquid or gel-like electrolyte used to collect the electrons. When a DC current is inputted on the tantalum capacitor, a condition of chemical equilibrium is created between the anode and the electrolyte, producing a layer of oxide on the anode, which acts as a dielectric material preventing conduction of current. This oxide layer is held together by the surface tension of the liquid electrolyte, forming an energy storage system.

In summary, the 173D226X5015XW is a Tantalum capacitor specifically designed for use in a wide variety of different applications, ranging from decoupling capacitors to high-voltage/low ESR voltage regulators. It stands out for its massive capacitance range, offering factors of up to 85 Volts and 2000 µF. Its working principle is based on an electrolyte solution which produces a layer of dielectric material on its anode, forming a reliable energy storage system.
