Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet electrical parameters against design requirements to validate performance under specific operating conditions.

Selection Notes

Select this component when high-density EMI filtering is required in space-constrained designs. The three-terminal structure offers superior noise rejection compared to standard two-terminal capacitors. Ensure PCB layout supports the specific grounding requirements inherent to feed-through capacitor operation for optimal filtering effectiveness.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which utilizes proprietary flexible termination materials. These terminations enhance mechanical reliability by absorbing stress during board flexing and thermal expansion cycles. The series is engineered for robust performance in demanding environments where conventional ceramic capacitors might fail due to mechanical strain.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 50V rating, 22nF capacitance, and three-terminal configuration. Verify that alternative components support similar temperature ranges and offer comparable flexibility in their termination structures to maintain assembly reliability.
