NOJA476M002RWJ

Overview

The NOJA476M002RWJ is a solid niobium oxide capacitor from the KYOCERA AVX NOJ series, designed for surface-mount applications. It features a capacitance of 47 µF with a DC voltage rating of 2.5 VDC and a tolerance of ±20%. The component utilizes a 1206 (3216 metric) case code, measuring 3.2 mm in length, 1.6 mm in width, and 1.8 mm in height. Key electrical parameters include an equivalent series resistance (ESR) of 1.6 Ohms and a leakage current of 3.8 µA. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide technology for high volumetric efficiency compared to traditional tantalum capacitors.
• Features a low-profile 1206 surface-mount package suitable for space-constrained PCB layouts.
• Provides stable performance across a wide operating temperature range of -55°C to +105°C.

Applications

• Portable consumer electronics requiring compact power filtering
• Automotive infotainment and control modules
• Industrial equipment with limited board space

Procurement Notes

Verify the specific suffix 'RJ' against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with standard reflow soldering profiles defined for niobium oxide components. Confirm RoHS compliance status through official certification documents prior to integration into production lines.

Selection Notes

Select this component when high capacitance density is required in a 1206 footprint. Compare ESR values against circuit ripple current requirements to ensure thermal stability. Evaluate leakage current limits against sensitive analog circuitry needs. Consider the 2.5V rating margin relative to maximum operating voltages in the target application environment.

Part Context

This part belongs to the NOJ series of niobium oxide capacitors manufactured by KYOCERA AVX. The series is engineered to offer higher capacitance per unit volume than conventional solid tantalum alternatives. It serves as a modern alternative for decoupling and filtering applications where size reduction is critical.

Replacement Considerations

Direct substitutes may include other niobium oxide capacitors in the 1206 package with matching 47µF/2.5V ratings. Verify ESR and physical dimensions before substitution. Cross-reference with TAJ or NOJE series parts only if form-factor and electrical tolerances align precisely with design constraints.
