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.
Modern Surface-Mount Tantalum Chip Capacitors. The compelling characteristics of tantalum capacitors are small size, high reliability, and good parametric performance over broad ranges of frequency and temperature. As mentioned earlier, the small size of tantalum capacitors results from the porous pressed powder structure of the capacitor element.
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.
Such low ESR in combination with high capacitance makes the tantalum polymer capacitor the fastest growing segment of the tantalum capacitor industry. The higher conductivity of the conductive polymer electrolyte improves the high-frequency capacitance of these capacitors.
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.
