Procurement Notes
Verify the complete part number including all suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet electrical parameters with design constraints to validate suitability for the intended application environment.
Selection Notes
Select this component when board space is limited but effective EMI filtering is required. The feed-through design offers superior noise attenuation compared to standard MLCCs in similar packages. Ensure the circuit current does not exceed the rated 2 A limit. Verify that the 25 VDC rating aligns with the maximum operating voltage of the target system.
Part Context
This component belongs to the Knowles Syfer FlexiCap series, which incorporates flexible terminations to reduce stress on ceramic elements during board flexing. The 1806Y prefix indicates a specific voltage and case code combination within the broader multilayer ceramic capacitor portfolio.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer catalogs for direct equivalents or parameter-matched alternatives.
