NOJA336M004SWJ

Overview

The NOJA336M004SWJ is a solid niobium oxide surface-mount capacitor from the OxiCap NOJ series by KYOCERA AVX. It features a capacitance of 33 µF with a DC voltage rating of 4 V and a tolerance of ±20%. The component utilizes an SMD/SMT termination type within a 1206 (3216 Metric) case size, measuring 3.2 mm in length, 1.6 mm in width, and 1.8 mm in height. Key electrical specifications include an equivalent series resistance (ESR) of 1.7 Ohms and a leakage current of 1.3 µA. It operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Utilizes non-burn-safe niobium oxide technology for enhanced reliability compared to traditional tantalum capacitors.
• Provides high volumetric efficiency through compact 1206 surface-mount packaging suitable for space-constrained designs.
• Offers stable performance across a wide operating temperature range from -55°C to +125°C.

Applications

• Portable consumer electronics requiring low-profile power filtering
• Automotive infotainment and safety systems
• Industrial equipment control circuits
• Wearable devices with strict space limitations

Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm it denotes the standard reel packaging configuration as listed in distributor catalogs. Ensure the requested quantity aligns with the manufacturer's standard reel pack size. Confirm that the 1206 footprint matches the target PCB layout dimensions precisely. Check for any recent obsolescence notices or lifecycle status updates directly from KYOCERA AVX before finalizing procurement orders.

Selection Notes

Select this component when a robust alternative to tantalum capacitors is required without sacrificing volumetric efficiency. The niobium oxide chemistry offers inherent safety advantages regarding failure modes. Consider the 1.7 Ohm ESR value for ripple current handling capabilities in the specific circuit application. The 4V rating provides a margin for stability in low-voltage digital logic power rails.

Part Context

This part belongs to the OxiCap NOJ series, which represents KYOCERA AVX's line of niobium oxide capacitors. These components are designed to address the limitations of solid tantalum capacitors, particularly regarding surge current sensitivity. The series is widely recognized for its reliability in automotive and industrial sectors where long-term stability and safety are critical requirements.

Replacement Considerations

Direct cross-replacement requires matching the 33 µF, 4V, 1206 form factor. Verify if other manufacturers offer niobium oxide equivalents with identical pinout and electrical characteristics. Standard tantalum replacements may require derating considerations due to different surge current behaviors.
