Procurement Notes
Verify the specific manufacturer datasheet for detailed electrical characteristics and reliability data before integration. Confirm that the niobium oxide construction aligns with your design requirements regarding surge current handling and failure modes. Ensure compliance with RoHS directives and check for any specific handling instructions related to moisture sensitivity levels.
Selection Notes
Select this component when high capacitance density is required in a 2917 footprint. Compare its 30 mOhm ESR against alternative tantalum or polymer capacitors to determine suitability for ripple current applications. Consider the 2.5V rating relative to circuit voltage peaks to ensure adequate derating margins for long-term stability.
Part Context
This part belongs to the NOME series of niobium oxide capacitors, offering an alternative to traditional solid tantalum components. It provides similar form factors while utilizing niobium pentoxide dielectric material. This series addresses the need for miniaturization in modern portable electronics without sacrificing performance.
Replacement Considerations
Direct substitutes include NOSD477M002R0100 and NOME477M002R0055. Verify compatibility by comparing ESR values, leakage current specifications, and physical dimensions to ensure fit within the existing PCB layout.
