Niobium Oxide Capacitors Procurement Notes

Verify current availability and lead times directly with KYOCERA AVX or authorized distributors, as this component may be subject to factory special order status. Confirm RoHS compliance and REACH status prior to procurement. Ensure proper handling procedures are followed due to the specified moisture sensitivity level (MSL 3). Validate that the 2917 footprint matches the target PCB design requirements before finalizing orders.

Niobium Oxide Capacitors Selection Notes

Select this component when high capacitance density is required in a low-profile form factor. The niobium oxide chemistry offers advantages over solid tantalum regarding surge current handling. Ensure the circuit voltage does not exceed the 4 VDC rating. Consider the 400 mOhm ESR for ripple current calculations. Verify compatibility with standard reflow soldering profiles for SMD/SMT assembly processes.

Niobium Oxide Capacitors Part Context

This part belongs to the OxiCap NOJ series, which represents KYOCERA AVX's line of low-profile niobium oxide capacitors. The series is designed to provide high capacitance values in compact surface-mount packages. The NOJD suffix indicates specific case dimensions and termination types within the broader NOJ family, targeting applications requiring reliable energy storage in limited board areas.

Niobium Oxide Capacitors Replacement Considerations

Direct substitutes within the same series include NOJD227M006RWJ for higher voltage ratings. Cross-technology replacements such as TAJX227M004RNJ (tantalum) require careful evaluation of ESR and surge current differences. Always verify pinout compatibility and thermal characteristics when considering alternative manufacturers' components.
