Reliability Effects with Proofing of Tantalum Capacitors

  title={Reliability Effects with Proofing of Tantalum Capacitors},
  author={Bill Long and Mike Prevallet and J. Prymak},
In traditional tantalum capacitors, the construction consists of a tantalum anode, Ta2O5 dielectric, and MnO2 as the cathode. The benefit of having MnO2, as the cathode, is the self-healing effect it provides. The conversion of MnO2 to a higher resistive state allows fault sites within the dielectric to be shut off from the rest of the capacitor. To mitigate problems developed during reflow, it is recommended for tantalum capacitors to be derated 50% for power-on reliability. Many times… CONTINUE READING
