NOJB476M006RWJ

Overview

The KYOCERA AVX NOJB476M006RWJ is a surface-mount Niobium Oxide capacitor from the NOJ series, branded as OxiCap. It features a capacitance of 47 µF with a ±20% tolerance and a DC voltage rating of 6.3 V. The component utilizes a 1210 (3225 Metric) package, measuring 3.2 mm in length, 2.5 mm in width, and 1.8 mm in height. Key electrical specifications include an Equivalent Series Resistance (ESR) of 1.6 Ohms, a ripple current rating of 168 mA, and a leakage current of 1.1 µA. It operates within a temperature range of -55°C to +105°C and meets AEC-Q200 automotive standards.

Feature Summary

• Utilizes Niobium Oxide technology for high volumetric efficiency compared to traditional tantalum capacitors.
• Complies with AEC-Q200 automotive qualification standards for reliability.
• Offers low profile construction suitable for space-constrained surface mount applications.

Applications

• Automotive electronics requiring AEC-Q200 compliant components
• Portable consumer devices needing high capacitance in small footprints
• General purpose DC-DC converter output filtering

Procurement Notes

Verify the specific suffix RWJ against the manufacturer datasheet to confirm packaging type and tape/reel specifications. Ensure the procurement channel provides traceable documentation confirming the component's origin from KYOCERA AVX. Cross-reference the lot code and date code to verify compliance with RoHS directives and current production status before finalizing orders.

Selection Notes

Select this component when a compact surface-mount solution is required that offers higher capacitance density than standard tantalum alternatives. The 6.3V rating and 1.6 Ohm ESR make it suitable for low-voltage filtering applications. Consider the 1210 footprint constraints and the specific thermal operating range of -55°C to +105°C during circuit design integration.

Part Context

This part belongs to the NOJ series of Niobium Oxide capacitors, marketed under the OxiCap brand by KYOCERA AVX. The series is designed to address the scarcity of tantalum materials while providing comparable performance characteristics. The NOJB476M006RWJ specifically represents the 47 µF variant within the 6.3V voltage class.

Replacement Considerations

Direct substitutes within the same series include NOJA476M006RWJ (different case size) or other NOJ variants with matching capacitance and voltage ratings. Verify pinout compatibility and physical dimensions when replacing with cross-brand equivalents.
