NOJB476M006RWJV

Overview

The NOJB476M006RWJV is a surface-mount niobium oxide capacitor from the KYOCERA AVX NOJ series. It features a capacitance of 47 µF with a tolerance of ±20% and a DC voltage rating of 6.3 V. The component utilizes a 1210 (3528 metric) package, measuring 3.5 mm in length, 2.8 mm in width, and 1.6 mm in height. Key electrical parameters include an equivalent series resistance (ESR) of 0.8 Ω, a dissipation factor of 6%, and a maximum leakage current of 1.2 µA. It supports a ripple current of 0.1 A and operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide technology for stable performance across wide temperature ranges.
• Designed for surface-mount applications with a low-profile 1210 footprint.
• Complies with automotive reliability standards including AEC-Q200 certification.

Applications

• Automotive electronics requiring robust capacitors under AEC-Q200 standards
• Portable consumer devices utilizing space-constrained surface-mount layouts
• Industrial control systems operating within extended temperature environments

Procurement Notes

Verify the specific suffix RWJV against official datasheets to confirm package dimensions and termination type. Ensure compliance with RoHS directives and check for AEC-Q200 qualification if automotive use is intended. Confirm that the 6.3V rating aligns with circuit requirements to prevent overvoltage stress.

Selection Notes

Select this component when a compact surface-mount solution is required for moderate capacitance values. The 1210 package offers a balance between size and current handling capabilities compared to smaller footprints. Consider the ESR and leakage specifications for filtering or decoupling applications where stability is critical.

Part Context

This part belongs to the NOJ series of niobium oxide capacitors, which serve as alternatives to tantalum capacitors in many applications. The series is characterized by its ability to handle high ripple currents and its reliability in harsh environments. The NOJB variant specifically denotes the 1210 package style within this product line.

Replacement Considerations

Direct substitutes may include other niobium oxide capacitors from the same manufacturer with identical electrical ratings and package dimensions. Cross-reference with TAJ series tantalum capacitors only if voltage derating and ESR differences are accounted for in the design.
