NOJD337M004SWJ

Overview

The NOJD337M004SWJ is a solid niobium oxide surface-mount capacitor from the OxiCap NOJ series by KYOCERA AVX. It features a nominal capacitance of 330 µF with a DC voltage rating of 4 V and a tolerance of ±20%. The component utilizes a 2917 (7343 metric) case package, measuring 7.3 mm in length, 4.3 mm in width, and 2.9 mm in height. Key electrical specifications include an equivalent series resistance (ESR) of 300 mΩ and a leakage current of 26.4 µA. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Utilizes niobium oxide technology to provide high volumetric efficiency compared to traditional tantalum capacitors.
• Compliant with AEC-Q200 automotive reliability standards for robust performance in demanding environments.
• Features low equivalent series resistance (ESR) suitable for high-frequency decoupling applications.

Applications

• Automotive electronics systems requiring AEC-Q200 qualified components
• Mobile device power supply filtering
• Industrial equipment control circuits

Procurement Notes

Verify that the specific suffix SWJ corresponds to the required tape and reel packaging configuration as defined in the official datasheet. Confirm that the niobium oxide chemistry aligns with project requirements regarding surge current handling capabilities. Ensure that the 4V rating provides sufficient derating for the target application circuit conditions.

Selection Notes

Select this component when high capacitance density is required in a 2917 footprint. The niobium oxide material offers better surge current tolerance than standard tantalum types. Consider the 300 mΩ ESR value for ripple current calculations. Verify compatibility with standard reflow soldering profiles for SMD/SMT termination types.

Part Context

This part belongs to the OxiCap NOJ series, which represents KYOCERA AVX's niobium oxide capacitor line. These components are designed as alternatives to tantalum capacitors, offering similar form factors with improved safety margins against thermal runaway. The series targets applications needing stable capacitance in compact spaces.

Replacement Considerations

The NOSD337M004R0100 is a niobium oxide alternative but differs in ESR (100 mΩ) and physical dimensions (7343 vs 7343 metric, though both are 2917 style, verify exact pinout). The TAJC337M004RNJ is a tantalum capacitor with different electrical characteristics and failure modes; substitution requires careful review of surge current limits and polarity sensitivity.
