NPVV477M004R0003

Overview

The NPVV477M004R0003 is a niobium oxide capacitor from the CoreCap NPV series, manufactured by KYOCERA AVX. It features a capacitance of 470 µF with a ±20% tolerance and a rated DC voltage of 4 V. The component utilizes a 2924 (7361 metric) surface-mount package, measuring 7.3 mm in length, 6.1 mm in width, and 3.5 mm in height. It exhibits an extremely low equivalent series resistance (ESR) of 3 mΩ, supporting high ripple current applications. The device operates within a temperature range of -55°C to +125°C and includes moisture sensitivity protection.

Feature Summary

• Ultra-low ESR design for high-frequency performance
• High reliability niobium oxide construction
• Extended operating temperature range up to 125°C

Applications

• Portable electronic devices requiring compact power filtering
• Mobile communication modules
• Consumer electronics with space constraints

Procurement Notes

Verify the specific suffix R0003 against official KYOCERA AVX documentation to confirm reel packaging specifications and moisture sensitivity classification. Ensure compatibility with standard reflow soldering profiles for 2924 packages. Cross-reference RoHS compliance status directly with the manufacturer's latest environmental declaration before integration into production lines.

Selection Notes

Select this component when ultra-low ESR is critical for noise reduction in low-voltage circuits. The 4V rating suits systems with tight voltage margins. Compare physical dimensions against PCB footprint requirements. Consider niobium oxide advantages over tantalum regarding surge current handling and cost efficiency for high-capacitance values in small footprints.

Part Context

This part belongs to the CoreCap NPV series, representing KYOCERA AVX's niobium oxide capacitor line. Niobium oxide technology offers higher volumetric efficiency compared to traditional tantalum capacitors. The series is designed for applications demanding high reliability and low impedance in compact form factors, bridging the gap between ceramic capacitors and solid electrolytic types.

Replacement Considerations

Direct substitutes include NOJD477M004RWJ and NOSD477M004R0100 from the same manufacturer. Verify ESR differences: NOJD has 300 mΩ ESR, while NOSD has 100 mΩ ESR. Both are niobium oxide but differ significantly in impedance characteristics. Tantalum alternatives like TAJY477M004RNJ have higher ESR (400 mΩ) and require careful derating analysis.
