Tantalum ore is one of the conflict minerals. It consists of a pellet tantalum metal as anode covered by insulating oxide layer that forms the dielectric surrounded liquid solid electrolyte cathode [...]
Impedance. A particular cause of confusion is that surface mount tantalum capacitors the positive terminal marked with bar. ESR and dissipation factor tan edit Typical impedance curves as function of frequency temperature over for different electrolytic capacitor styles compared with MLCC The equivalent series resistance summarizes all resistive losses . At increased temperatures chemical reaction then reduces surrounding conductive manganese dioxide to insulating III MnO and insulates crystallized tantalum layer stopping local current flow [...]
Tantalum electrolytic capacitors with solid electrolyte are marked at their positive terminal bar . This oxide layer serves as the dielectric in an electrolytic capacitor. end new Date Image c Url if var . If the capacitor s inductance ESL is small dissipation factor can be approximated as ESR displaystyle delta mbox cdot omega used for capacitors with very low losses frequency determining circuits resonant where reciprocal value of called quality which represents resonator bandwidth [...]

Electrolytic capacitors differ from other types whose capacitances are typically measured at kHz higher. Due to their selfhealing properties nonsolid electrolyte can deliver oxygen form new oxide layer weak areas of dielectric thickness be formed with much lower safety margins and consequently thinner than types resulting higher CV value volume unit [...]
When subjected to reversed polarity even briefly the capacitor depolarizes and dielectric oxide layer breaks down which can cause fail later operated with correct . Nonpolar or bipolar tantalum capacitors are made by effectively connecting two polarized series with the anodes oriented opposite directions. The category voltage is maximum DC peak pulse that may be applied continuously to capacitor any temperature within range TC [...]
