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.
SMD tantalum capacitors are a close match to the standard MLCC case sizes, thanks to which MLCCs could be replaced with tantalum capacitors without the need to change the PCB footprint. In the case of tantalum capacitors, not only length and width are indicated in terms of dimensions (as in MLCCs) but also height.
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.
Tantalum capacitators are polarized due to reactions which take place during the forming of the dielectric layer, as the layer of oxide, which acts as a semiconductor, forms between tantalum oxide and pure tantalum. The dielectric layer is formed at a voltage higher than the operating 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.
In most applications, the capacitors are easily recharged to replenish the charge lost to leakage, and is of no concern. Wet tantalum capacitors: These can work at high voltages, from 100V to 630 V, with low ESR and lowest leakage current among electrolytic capacitors.
