Tantalum capacitor, full name is tantalum electrolytic capacitor .It is a kind of electrolytic capacitor. It uses metal tantalum as a medium. Unlike ordinary electrolytic capacitors, it uses electrolyte. Therefore, it is suitable for working at high temperatures. It is a small-capacity product in a capacitor that can achieve a large capacitance.
In addition to the nice gain in capacitance per volume, the tantalum capacitors also have very low ESR or Equivalent Series Resistance reducing system losses. A downside of low ESR is that it may be too low to achieve stability in power supply regulators, which needs to be taken into account. Why Use Tantalum Capacitors?
But solid electrolytic capacitors can work above 50kHz. Tantalum capacitors will also decrease in capacity as the frequency increases, but the decrease is small. Some data show that the capacity of tantalum capacitors decreases by less than 20% when working at 10kHz, while the capacity of aluminum electrolytic capacitors decreases by 40%.
The biggest risk with tantalum/nobium capacitors are surges and any reverse polarity at all. These risks can be largely mitigated by generously overrating their voltage. Doubling is a good start. AVX has some good white papers on this stuff. Re: When/why (not) to use Tantalum capacitors.
