What are Tantalum Capacitors?

Tantalum capacitors are small, cylindrical components with two electrically isolated terminals. They are composed of tantalum electrodes with an electrolyte so they are called tantalum electrolytic capacitors, and are widely used in electronic circuits due to their low profile, lightweight and high-temperature and frequency performance stability.

Tantalum capacitors are usually characterized based on their maximum voltage rating, temperature and frequency performance, capacitance, thickness, tolerance and other parameters. Among these parameters, the most commonly used type is T95D157M016LSAL, which will be discussed throughout this article.

Application Field

T95D157M016LSAL is the widely-used model of tantalum capacitor. It mainly application in defense, aerospace, medical, and automotive industry, etc. It Applications include output filters for ICs, decoupling capacitors for DC-to-DC converters, power supplies, computers and other electronic applications. Moreover, it also used in the anti-reverse circuit.

Working Principle

The basis of the operation of the capacitor is that the dielectric layer between two metal plates stores an electric charge when a voltage is applied. This electric charge is measurable and a capacitor passes an alternating current at a specified frequency. When two tantalum electrodes are immersed in an electrolytic solution, a reaction between the electrolyte and the electrolyte takes place and a thin oxide layer is built up between the electrodes. This thin oxide layer shows dielectric properties and is instead of the element between the two electrodes and let them with high leakage current. Compared with other capacitors, the voltage can be higher, the leakage rate is low, and the signal interference is low.

T95D157M016LSAL consists of a sintered tantalum anode and a cathode. The anode is a compact sheet of tantalum particles, coated with an oxide dielectric material on the surface. The cathode is made up of tin-lead alloy, and the oxide dielectric layer between the anode and cathode is maintained by the electrolyte. When the voltage is applied, the oxide layer creates a field that increases the capacitance and allows current to flow between the electrodes. The capacitance of the capacitor also depends on the amount of electric charge that has been stored in the oxide layer and the voltage that is applied.

In conclusion, Tantalum capacitor T95D157M016LSAL is widely used in defense, aerospace, medical, and automotive industry. It\'s operational principle is based on the build up of an oxide layer on the tantalum particles and its capacitance is based on the amount of electric charge stored in the oxide layer and the voltage that is applied to the device.
