Procurement Notes

Verify the specific suffix codes against official datasheets to confirm tolerance, temperature range, and termination finish. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Cross-reference part numbers carefully as minor variations may affect electrical characteristics or mechanical fit. Confirm availability through authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when high capacitance values are required at low voltages within strict spatial constraints. Consider the ESR specifications for ripple current handling capabilities. Evaluate thermal performance requirements against the rated operating temperature range. Ensure the voltage derating aligns with system operational peaks to maintain reliability margins.

Part Context

This part belongs to the NOJD series of solid tantalum capacitors designed for general-purpose applications. The series emphasizes miniaturization and low impedance characteristics. It complements other KYOCERA AVX offerings by providing robust performance in portable devices where size and weight are critical factors. The technology leverages manganese dioxide solid electrolytes for consistent electrical behavior.

Replacement Considerations

Direct replacements must match the 470 µF capacitance, 4 V rating, and 3.2x2.5x1.6 mm package dimensions. Verify that substitute components offer comparable ESR levels and ripple current ratings. Check for pinout compatibility if alternative packages are considered. Consult manufacturer cross-reference guides for validated equivalents.
