ESR is a critical parameter for tantalum capacitors, particularly in high-frequency applications. A low ESR helps maintain efficiency and reduces power loss,
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.
They represented a quantum leap forward in miniaturization and reliability over existing wound-foil wet electrolytic capacitors. While the solid tantalum capacitor has dramatically improved electrical performance versus wet-electrolyte capacitors, especially at low temperatures, today’s electronic circuits require even better performance.
The stability and resistance to elevated temperatures of the tantalum / tantalum oxide / manganese dioxide system make solid tantalum capacitors an appropriate choice for today's surface mount assembly technology.
When tantalum capacitor is used at high frequency circuit, please note that the electrical characteristics may change drastically. Leakage current value differs depending on the voltage applied. Please use higher ratings, especially when it is used in the integration circuit or time-constant circuit.
In solid tantalum electrolytic capacitors the heat generated by the ripple current influences the reliability of the capacitors. Exceeding the limit tends to result in catastrophic failures with shorts and burning components.
However, tantalum polymer capacitors do fail in the short-circuit mode, and if the available current from the circuit is substantial, it is possible to achieve sustained combustion of the capacitor and of the surrounding circuitry simply due to the substantial heat generated by the high fault currents.
