Tantalum electrolytic capacitors have been on the market for more than half a century, in a range of applications. However, the most common design uses MnO 2 as the electrolyte, which can be thermodynamically unstable and, upon failure, can damage the circuit.
Tantalum capacitors are reliable components. Continuous improvement in tantalum powder and capacitor technologies have resulted in a significant reduction in the amount of impurities present, which formerly have caused most of the field crystallization failures.
As the dielectric constant of the tantalum pentoxide and area of the plates are large, resulting in very high capacitance of a tantalum capacitor: The tantalum pellet along with the attached tantalum wire form the anode (positive) plate. The external anode lead wire is welded to the tantalum wire.
By using tantalum capacitor markings on the body of a component, one can easily identify the positive and negative terminals. The standard polarized capacitor symbol for a polarized capacitor serves as a visual guide for the proper orientation of the component in circuit diagrams.
This oxide, tantalum pentoxide, has a dielectric constant of 26. The tantalum metal serves as the anode, and the cathode is usually made of a conductive material, often manganese dioxide in traditional tantalum capacitors. Another name for a wet tantalum capacitor is liquid tantalum capacitor or non-solid tantalum capacitor.
