Overview
The NOJB476M001RWJ is a low-profile niobium oxide capacitor from the OxiCap NOJ series, manufactured by KYOCERA AVX. It features a capacitance of 47 uF with a DC voltage rating of 1.8 VDC and a tolerance of 20%. The component utilizes an SMD/SMT termination type within a 1210 (3528 metric) package, measuring 3.5 mm in length, 2.8 mm in width, and 1.8 mm in height. Key electrical parameters include an ESR of 1.6 Ohms, leakage current of 1.7 uA, and ripple current capability of 237 mA. It operates within a temperature range of -55 C to +105 C.
Feature Summary
- Utilizes niobium oxide technology for high volumetric efficiency in compact surface-mount designs.
- Features a low-profile form factor suitable for space-constrained electronic applications.
- Provides stable performance across a wide operating temperature range.
Applications
- Mobile devices and smartphones requiring high capacitance in small footprints
- Tablets and portable consumer electronics
- Automotive infotainment and safety equipment systems
Procurement Notes
Verify the specific suffix RWJ against the manufacturer's latest datasheet to confirm packaging details and reel specifications. Ensure that the 1.8V DC rating aligns with the circuit design requirements, as niobium capacitors are sensitive to overvoltage conditions. Confirm RoHS compliance status through official documentation before finalizing procurement orders.
Selection Notes
Select this component when high capacitance density is required in a 1210 footprint for low-voltage applications. Compare the 1.6 Ohm ESR against circuit filtering needs. Consider the 1.8V rating limit strictly; do not exceed this voltage. Evaluate thermal management capabilities given the +105 C maximum operating temperature and self-heating effects under ripple current loads.
Part Context
This part belongs to the OxiCap NOJ series, representing KYOCERA AVX's niobium oxide capacitor line. These components bridge the gap between tantalum and ceramic technologies, offering higher capacitance than MLCCs in similar packages while maintaining better reliability characteristics than some solid tantalum alternatives for low-voltage use cases.
Replacement Considerations
The NOJA476M001RWJ serves as a verified substitute within the same NOJ series, differing only in package dimensions (1206 vs 1210). Verify mechanical fitment on the PCB layout before substitution. No other direct cross-model replacements are confirmed in public documentation.
