The MnO 2 cathode has a property that significantly contributes to tantalum capacitor reliability. Defects in the Ta 2 O 5 dielectric cause local heating at the defect site during capacitor operation, which changes the nearby MnO 2 to Mn 2 O 5 — a non-conductive phase of manganese oxide. This non-conductive site serves to remove that portion of the capacitor from the circuit, … - Download [PDF]
