Niobium Oxide Capacitors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and compliance documentation prior to integration. Note that this specific part number is listed as obsolete; ensure availability of alternative sources or qualified substitutes if long-term supply continuity is required for production planning.

Niobium Oxide Capacitors Selection Notes

Select this component when high volumetric efficiency is needed alongside moderate voltage ratings. The niobium oxide material offers advantages over traditional tantalum in terms of surge current handling. Ensure the application circuit respects the 6.3V rating and accounts for the 75 mOhm ESR for ripple current management within the specified temperature range.

Niobium Oxide Capacitors Part Context

This part belongs to the OxiCap NOJ series, representing KYOCERA AVX's portfolio of niobium oxide capacitors. These components are engineered to provide reliable performance in space-constrained applications where standard tantalum capacitors may be less suitable due to surge limitations. The series targets industries requiring robust passive components for modern electronic designs.

Niobium Oxide Capacitors Replacement Considerations

The product status is officially listed as Obsolete. Designers should evaluate alternative niobium oxide or solid tantalum capacitors with matching 470 µF, 6.3V, and 2917 package dimensions. Verify pin compatibility and electrical parameter equivalence before substitution.
