NOJB107M004RWJ

Overview

The NOJB107M004RWJ is a low-profile niobium oxide capacitor from the KYOCERA AVX Oxicap series. It features a capacitance of 100 µF with a DC voltage rating of 4 V and a tolerance of ±20%. The component utilizes a 1210 (3528 metric) surface mount package, measuring 3.5 mm in length, 2.8 mm in width, and 1.9 mm in height. Key electrical characteristics include an equivalent series resistance (ESR) of 1.4 Ohms, a ripple current rating of 270 mA, and a leakage current of 3.6 uA. It operates within a temperature range of -55°C to +85°C.

Feature Summary

• Utilizes niobium oxide dielectric technology for high volumetric efficiency
• Designed as a low-profile surface mount component for space-constrained applications
• Offers stable performance with defined ESR and ripple current capabilities

Applications

• Portable consumer electronics requiring compact power filtering
• Mobile communication devices needing high capacitance in small footprints
• General-purpose DC-DC converter output filtering

Procurement Notes

Verify the specific voltage rating and physical dimensions against the official datasheet before integration, as niobium oxide capacitors have distinct voltage derating requirements compared to other dielectric types. Confirm that the operating temperature range aligns with the system environment, noting the maximum limit of 85°C. Ensure the PCB layout supports the 1210 footprint and accounts for the specified thermal characteristics during soldering processes.

Selection Notes

Select this component when a higher capacitance density is required than tantalum or aluminum electrolytic capacitors can provide in a similar volume. It serves as a suitable alternative where low profile and moderate voltage ratings are critical constraints. Consider the specific ESR value of 1.4 Ohms for circuit stability analysis. Evaluate the 4V rating against peak transient voltages to ensure adequate margin under all operating conditions.

Part Context

This part belongs to the NOJ series of low-profile niobium oxide capacitors manufactured by KYOCERA AVX. The series is marketed under the Oxicap trademark, focusing on providing high reliability and volumetric efficiency for modern electronic designs. These components are designed to replace bulkier alternatives in portable applications while maintaining robust electrical performance across the specified temperature range.

Replacement Considerations

Direct substitutes may include other niobium oxide capacitors from the same manufacturer with matching 100 µF, 4V, and 1210 specifications. Cross-referencing with other manufacturers' niobium oxide lines requires careful verification of ESR, leakage current, and mechanical dimensions to ensure functional compatibility.
