Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation before ordering. Confirm RoHS compliance status and specific termination finish requirements with the supplier. Ensure storage conditions align with moisture sensitivity level specifications to maintain component reliability during assembly processes.

Selection Notes

Select this component when high capacitance density is required within a standard 1206 footprint for EMI mitigation. The three-terminal design offers superior high-frequency performance compared to two-terminal equivalents. Consider the FlexiCap feature if the application involves significant mechanical stress or PCB warping during operation or assembly.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in robust MLCCs for demanding environments. The 1206Y prefix indicates the 1206 case size with specific electrical characteristics. As an EMI filter capacitor, it integrates shielding capabilities directly into the passive component structure, reducing the need for additional discrete filtering elements.
