Tantalum capacitors are the main use of the element tantalum. Tantalum ore is one of the conflict minerals. Some non-governmental organizations are working together to raise awareness of the relationship between consumer electronic devices and conflict minerals.
It is also of interest that because of the solid nature of the tantalum capacitor’s construction, there is no known wear out mechanism in tantalum capacitors. This paper has been written to provide the user of tantalum capacitors with an idea of the effect of design criteria on the capacitor and the methods used in their production.
In data sheets of electrolytic capacitors, only the impedance magnitude |Z| is specified, and simply written as "Z". Regarding to the IEC/EN 60384-1 standard, the impedance values of tantalum electrolytic capacitors are measured and specified at 10 kHz or 100 kHz depending on the capacitance and voltage of the capacitor.
The tests and requirements to be met by aluminum and tantalum electrolytic capacitors for use in electronic equipment for approval as standardized types are set out in the following sectional specifications: Tantalum capacitors are the main use of the element tantalum. Tantalum ore is one of the conflict minerals.
The steady-state and dynamic reliability of a tantalum capacitor are influenced by several factors under the control of the circuit design engineer. These factors are voltage derating, ripple current and voltage conditions, maximum operating temperature and circuit impedance.
As capacitors are being manufactured, a film of tantalum pentoxide is applied to their electrodes by means of an electrochemical process. The film is applied at various voltages resulting in various thicknesses, and although transparent to begin with, it takes on different colors as light refracts through it.
