Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation before ordering. Confirm that the specific revision matches project requirements. Check RoHS compliance status via the datasheet. Ensure storage conditions align with MLCC handling guidelines to prevent moisture damage prior to soldering.

Selection Notes

Select this component when board mechanical stress is a primary concern due to its flexible termination design. The three-terminal configuration offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 25V rating meets the circuit's maximum voltage peaks. Ensure the 1206 footprint is compatible with the PCB layout constraints.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with soft or flexible terminations. These devices are engineered to withstand mechanical stress during PCB bending or thermal cycling. The series targets applications where traditional rigid MLCCs are prone to cracking under strain.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching the 1206 footprint, 12 nF value, 25V rating, X7R dielectric, and three-terminal EMI filter topology.
