The key is to use them in applications where they will be safe. For power supply filtering they do little. Yes low esr, but you can parallel other caps to the same effect. Also there are high ripple low esr electrolytic caps. Typically orange outer jacket. Re: When/why (not) to use Tantalum capacitors. Pros, cons, alternatives
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?
Wet tantalum capacitors: These can work at high voltages, from 100V to 630 V, with low ESR and lowest leakage current among electrolytic capacitors. They have self-healing properties, allowing thinner dielectric oxide layer, and high capacitance per unit volume.
They have self-healing properties, allowing thinner dielectric oxide layer, and high capacitance per unit volume. Solid leaded tantalum capacitors: They have higher capacitance density than wet aluminium electrolytic capacitors or solid tantalum type. Higher electron conductivity makes them sensitive to voltage spikes or surge currents.
The primary structural difference between tantalum and aluminium can capacitors (other than the materials used) is the electrolyte. The electrolyte is a solid material in a tantalum capacitor, and a liquid in an aluminium can capacitor.
Voltage ratings of tantalum capacitors varies from 2V to greater than 500V. ESR value of this capacitor is 10 times less compare to aluminium electrolytic capacitor and hence it allows higher currents to pass through it with less heat. The typical specifications to be considered for selection of tantalum capacitors are as follows.
