Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, which is composed of tantalum oxide as an anode and an electrolyte. These components are named after the element tantalum, which is used in the anode. Tantalum capacitors are polarized components which feature very high capacitance values in a small form factor, with excellent stability and low leakage current. They are also used for stability and smoothing applications, and are ideally suited for use in high-reliability applications where reliability and long working life are essential components.

T491A105K016AT7111 application field and working principle

T491A105K016AT7111 is a type of tantalum capacitor and is used in a wide range of applications, from signal processing and computer systems, to power supplies and automotive applications. This particular type of capacitor has high capacitance density, low ESR, and low leakage current. It is also capable of meeting military standards and is ideal for applications where a high level of reliability is required.

The working principle behind a tantalum capacitor is based on a physical phenomenon known as electrochemical oxidation. This process occurs when an electrochemical cell is placed in contact with an electrolyte. A voltage is applied to the cell, and the ions within the electrolyte are attracted to the cathode. As the molecules of the electrolyte come into contact with the negative electrode, they are oxidized by the negative charges, creating an opposite reaction in the positive electrode. This reaction causes a charge to build up in the capacitor, and the capacitance is the product of the amount of charge stored in the capacitor and the voltage used to charge the capacitor.
