Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm terminal plating and packaging details. Ensure compatibility with PCB footprint dimensions and reflow soldering profiles specified in the datasheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components and confirm current production status.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency noise attenuation. The three-terminal design offers superior performance compared to standard two-terminal MLCCs in EMI applications. Consider the 1806 package size relative to available board space and thermal management requirements during layout planning.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which integrates capacitor functionality directly into the termination structure. These devices are engineered for applications requiring minimal impedance at high frequencies, distinguishing them from conventional multilayer ceramic capacitors by their unique internal electrode arrangement and grounding mechanism.

Replacement Considerations

Consult official substitution guides for equivalent three-terminal feed-through capacitors with matching capacitance, voltage rating, and package dimensions. Verify that alternative parts maintain similar frequency response characteristics and thermal stability profiles.
