Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation. Confirm that the receiving facility has appropriate handling procedures for surface-mount components. Ensure storage conditions align with manufacturer guidelines to maintain moisture sensitivity levels prior to soldering. Cross-reference the datasheet version with the latest official documentation from KYOCERA AVX to confirm compliance with current specifications.

Selection Notes

Select this component when niobium oxide chemistry is preferred over tantalum for improved surge capability and reliability. Consider the 2312 package dimensions for board space constraints. Evaluate the 0.3 ohm ESR against circuit ripple current requirements. Ensure the 6.3 VDC rating provides adequate derating for the target application voltage. Compare leakage current specifications against sensitive analog circuit needs.

Part Context

This part belongs to the OxiCap NOS series, which utilizes niobium oxide dielectric material. This technology addresses limitations associated with traditional manganese dioxide solid tantalum capacitors, particularly regarding surge current handling and long-term stability. The series is engineered for applications demanding high reliability and consistent performance across wide temperature ranges.

Replacement Considerations

Direct replacements must match the 47 µF capacitance, 6.3 VDC rating, and 2312 footprint. Verify ESR compatibility if ripple current filtering is critical. Niobium oxide alternatives may offer different surge characteristics. Tantalum equivalents require careful evaluation of surge current limits and failure modes. Consult KYOCERA AVX for validated substitute part numbers within the same or compatible series.
