NOJA226M004RWJ

Overview

The KYOCERA AVX NOJA226M004RWJ is a solid niobium oxide capacitor from the OxiCap NOJ series, designed for surface-mount applications. It features a capacitance of 47 µF with a ±20% tolerance and a DC voltage rating of 4 VDC. The component utilizes 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 2.2 Ohms, a leakage current of 3.8 µA, and a ripple current rating of 202 mA. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide technology to provide high volumetric efficiency in a compact footprint.

Applications

• Portable consumer electronics requiring space-constrained power filtering
• Automotive infotainment and safety equipment modules
• Industrial control systems needing reliable decoupling

Procurement Notes

Verify the specific suffix RWJ against the manufacturer's official datasheet to confirm the exact packaging configuration and tape-and-reel specifications. Ensure that the selected variant matches the required ESR and leakage current parameters for the target circuit design. Cross-reference the RoHS compliance status and moisture sensitivity level (MSL) requirements with assembly guidelines before procurement.

Selection Notes

Select this component when a higher capacitance density than tantalum capacitors is required in a 1206 package. Consider the 4V rating and 2.2 Ohm ESR for low-voltage digital logic decoupling or power rail smoothing. Evaluate the operating temperature range up to 105°C against environmental conditions. Compare performance metrics with alternative niobium oxide variants if different voltage ratings are needed.

Part Context

This part belongs to the KYOCERA AVX OxiCap NOJ series, which represents a line of solid niobium oxide capacitors. These components are engineered as alternatives to traditional tantalum capacitors, offering improved reliability and surge handling capabilities. The series is widely utilized in modern electronic designs where miniaturization and stable performance under varying thermal conditions are critical priorities.
