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
For most electrical circuit applications, MnO2 tantalum capacitors are a good choice. They have been proven in use for several decades, so their characteristics and reliability are well understood. They have a high volumetric efficiency (CV) and very stable parameters.
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.
According to Fig. 3, wet tantalum capacitors do not require derating up to 85 °C and only about 30 % derating at 125 °C. Wet tantalum capacitors continue to be widely used primarily in the AMS and oil and gas exploration markets.
Tantalum electrolytic capacitors have also less leakage and higher frequency response than aluminum electrolytic capacitors. Therefore, tantalum electrolytic capacitors are preferred in various electronic applications where small size and higher-frequency operation is required.
They are rated for low voltages, which not of concern since working voltages are low in most electronic circuits. These are extensively used in electronic circuits, laptops, mobile phones, automobiles as also military equipment due to their small size as also reliability. Tantalum capacitors commonly have voltage ratings below 35 V.
