NOSE477M004R0075

Overview

The KYOCERA AVX NOSE477M004R0075 is a Niobium Oxide capacitor from the NOS series, housed in a 2917 (7343 metric) surface-mount package. It offers a capacitance of 470 µF with a DC voltage rating of 4 V and a tolerance of ±20%. The component features an equivalent series resistance (ESR) of 75 mΩ, a leakage current of 37.6 µA, and a ripple current capability of 1.625 A. It operates within a temperature range of -55°C to +125°C and has physical dimensions of 7.3 mm length, 4.3 mm width, and 4.1 mm height.

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.
• Supports operation at elevated temperatures up to +125°C for robust performance.

Applications

• High-density power supply output filtering
• Decoupling in mobile devices and wearables
• General-purpose surface-mount circuitry requiring high capacitance

Procurement Notes

Verify availability status as the component is listed as discontinued by the manufacturer. Confirm that alternative sourcing channels or distributors are authorized to prevent counterfeit parts. Ensure compliance with RoHS standards and check for moisture sensitivity classification requirements during storage and handling prior to assembly.

Selection Notes

Select this component when high capacitance density is required in a 2917 footprint. Compare ESR values against circuit ripple current requirements to ensure thermal stability. Verify that the 4V DC rating provides sufficient margin for the operating voltage. Consider the -55°C to +125°C temperature range for environmental suitability.

Part Context

This part belongs to the NOS series of Niobium Oxide capacitors manufactured by KYOCERA AVX. These components are designed as alternatives to tantalum capacitors, offering similar electrical characteristics with improved safety profiles regarding failure modes. The Oxicap branding indicates a focus on low ESR performance within the niobium oxide category.

Replacement Considerations

NOSD477M004R0100: Similar 470µF 4V niobium oxide capacitor in 2917 package but with higher ESR (100mΩ). TAJE477M004RNJ: Tantalum solid capacitor with same capacitance and voltage but significantly higher ESR (500mΩ).
