Capacitor Manufacturing Best Practices for Increasing Profitability
Vertical Integration of Tantalum Powder and Wire Production. It is difficult to find cost savings for the production of tantalum capacitors, because unlike the other capacitor dielectrics, it is extremely difficult to produce capacitor grade tantalum metal powder, requiring a level of expertise that is considered advanced among metallurgists.
High-Reliability Solid Tantalum Capacitors
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 …
