NOJV477M006RWJ

Overview

The KYOCERA AVX NOJV477M006RWJ is a surface-mount niobium oxide capacitor from the Oxicap series. It features a capacitance of 470 uF with a DC voltage rating of 6.3 VDC and a tolerance of 20%. The component utilizes a 2924 (7361 metric) case package, measuring 7.3 mm in length, 6.1 mm in width, and 3.8 mm in height. Key electrical specifications include an equivalent series resistance (ESR) of 300 mOhms and a leakage current of 56.4 uA. It supports a ripple current of 775 mA and operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide technology for high volumetric efficiency in compact surface-mount designs.
• Provides low equivalent series resistance to support high-frequency decoupling applications.
• Offers robust performance across a wide industrial operating temperature range.

Applications

• Power supply output filtering
• High-density circuit board decoupling
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'V' indicates the Case V dimensions (7361 metric) distinct from other NOJ variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity levels as specified in the datasheet to maintain component reliability during assembly processes.

Selection Notes

Select this component when high capacitance is required in a standard 2924 footprint where niobium oxide offers advantages over tantalum. Compare ESR and ripple current ratings against circuit requirements. Consider thermal derating curves for operation near the maximum 105°C limit. Validate that the 6.3V rating provides sufficient margin for the application's peak voltage conditions.

Part Context

This part belongs to the KYOCERA AVX NOJ series of low-profile niobium oxide capacitors. The series is designed to replace traditional tantalum capacitors in space-constrained applications. The NOJV477M006RWJ specifically represents the 6.3V variant within the 470uF capacity tier, utilizing the Case V package geometry for standardized surface-mount placement.

Replacement Considerations

NOJD477M004RWJ differs by voltage rating and case size. NOJE477M006RWB uses a different case dimension (7343 metric). TAJV477M006RNJ is a tantalum alternative with different electrical characteristics. Verify mechanical fit and electrical parameters before substitution.
