NOJC227M004RWJ

Overview

The NOJC227M004RWJ is a Niobium Oxide capacitor from the OxiCap NOJ series by KYOCERA AVX. It features a capacitance of 220 µF with a ±20% tolerance and a DC voltage rating of 4 VDC. The component utilizes an SMD/SMT termination type within a 2917 (7343 metric) case size, measuring 7.3 mm in length, 4.3 mm in width, and 2 mm in height. Key electrical specifications include an Equivalent Series Resistance (ESR) of 400 mOhms, a leakage current of 17.6 µA, and a dissipation factor of 8%. It operates within a temperature range of -55°C to +105°C and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Utilizes niobium oxide technology for high volumetric efficiency compared to traditional tantalum capacitors.
• Offers low equivalent series resistance (ESR) suitable for high-frequency decoupling applications.
• Compliant with RoHS3 standards and REACH regulations for environmental safety.

Applications

• Smart meter applications
• Alternate energy systems
• Consumer electronics requiring compact power filtering

Procurement Notes

Verify the specific suffix 'C' against manufacturer documentation to confirm exact physical dimensions and lead time requirements. Confirm moisture sensitivity handling procedures are followed upon receipt. Ensure the application circuit voltage does not exceed the 4 VDC rating under all transient conditions. Cross-reference the datasheet for any recent updates regarding compliance declarations or material changes.

Selection Notes

Select this component when space constraints require a smaller footprint than standard tantalum equivalents while maintaining similar capacitance values. Consider the 400 mOhm ESR for ripple current capabilities in the target circuit. Evaluate the -55°C to +105°C operating range against the environmental conditions of the end product. Compare leakage current specifications against sensitive input stages if used in signal conditioning paths.

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 solid tantalum capacitors, offering improved surge capability and lower cost in many applications. The series is targeted at industrial and consumer markets needing reliable surface-mount solutions.

Replacement Considerations

NOJD227M004RWJ is a documented variant within the same NOJ series with identical electrical parameters but potentially different packaging or terminal configurations. Verify mechanical compatibility before substitution. Other niobium oxide parts from the same family may offer different voltage ratings or capacitance values.
