NOSD477M004R0100

Overview

The NOSD477M004R0100 is a Niobium Oxide capacitor from the Oxicap Low ESR series by KYOCERA AVX. It features a capacitance of 470 µF with a DC voltage rating of 4 VDC and a tolerance of ±20%. The component exhibits an equivalent series resistance (ESR) of 100 mOhms and supports a ripple current of 1.342 A. Housed in a 2917 (7343 Metric) surface-mount package measuring 7.3 x 4.3 x 2.9 mm, it operates within a temperature range of -55°C to +125°C. Leakage current is specified at 37.6 µA.

Feature Summary

• Utilizes niobium oxide technology for high volumetric efficiency compared to traditional tantalum capacitors.
• Provides low equivalent series resistance (ESR) suitable for high-frequency decoupling applications.
• Features solid electrolyte construction ensuring stable performance across wide temperature ranges.

Applications

• High-density portable electronic devices requiring compact power filtering.
• Mobile communication equipment utilizing surface-mount assembly.
• Automotive electronics systems demanding reliable energy storage.

Procurement Notes

Verify moisture sensitivity classification prior to soldering, as the component requires controlled handling during reflow processes. Confirm that the 2917 footprint matches the target PCB design constraints. Ensure supply chain sources provide original manufacturer documentation to validate the specific ESR and leakage current parameters listed in the official datasheet.

Selection Notes

Select this component when space constraints necessitate a smaller form factor than tantalum alternatives while maintaining similar capacitance values. The 4V rating limits suitability to low-voltage logic rails or battery-backed circuits. Consider the 100 mOhm ESR for ripple current requirements in switching regulator output stages.
