Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct specification alignment. Confirm RoHS compliance status and specific packaging options such as cut tape or reel availability through authorized distribution channels prior to procurement.

Selection Notes

Select this component when high capacitance density is required in a compact 1806 footprint for EMI applications. The X7R dielectric offers higher volumetric efficiency compared to Class 1 materials, while the three-terminal design provides superior high-frequency attenuation characteristics for noise-sensitive environments.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered for surface-mount applications requiring reliable EMI filtering. The 1806 case size balances physical space constraints with electrical performance needs, making it suitable for modern dense PCB layouts where standard two-terminal capacitors may be insufficient for noise control.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement maintains the 1806 footprint, 25V rating, and 180nF capacitance value while ensuring equivalent three-terminal EMI filtering capabilities.
