A wet tantalum capacitor is made by pressing tantalum powder into a shape and sintering it. Then, an electrochemical reaction forms the tantalum pentoxide as the dielectric, which results in the formation of the anode slug.
Vishay is a pioneer and leader in this field, producing a large variety of solid and wet tantalum capacitor types for industrial, automotive, medical, military, and aerospace electronic applications. Tantalum is not found in its pure state. Rather, it is commonly found in a number of oxide minerals, often in combination with Columbium ore.
Construction of typical MnO2 solid electrolyte tantalum capacitor The following manufacturing process chart describes common tantalum chip MnO2 solid electrolyte manufacturing flow. The process is identical also for niobium and NbO chip capacitors. The powder is compressed around a tantalum wire (known as the riser wire) to form a “pellet”.
Wet slug tantalum capacitors are manufactured in a voltage range up to 150 VDC. In choosing between the solid or wet style of tantalum capacitor, the circuit designer customarily uses wet tantalum capacitors, where the lowest DC leakage is required. The conventional silver can design will not tolerate any reverse voltages.
The dielectric used in all tantalum electrolytic capacitors is tantalum pentoxide. Tantalum pentoxide compound possesses high dielectric strength and a high dielectric constant. As capacitors are being manufactured, a film of tantalum pentoxide is applied to their electrodes by means of an electronic process.
