A tantalum capacitor is one kind of electrolytic capacitor, which is a passive electrical device. It uses a capsule of spongy tantalum metal as an anode. An insulating layer of oxide covers the anode. The oxide layer further generates the dielectric. It is surrounded by a solid or non-solid electrolyte, which serves as a cathode.

07/10/2022 · You DO NOT want to use tantalum caps on power supply lines that have high current limits. The result CAN BE FIRE. Tantalum caps frequently develop pin-holes in the dielectric, internally. These holes self-repair if the available current is not too high. No, I don't know what "too high" is, but USB tends to be current limited.
