Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and termination plating specifications. Ensure that the selected variant meets all required environmental certifications, such as RoHS compliance, for your target market. Cross-reference the datasheet for precise handling instructions regarding moisture sensitivity levels before assembly.

Selection Notes

Select this component when board flexibility is a primary concern due to its flexible terminal construction. The C0G dielectric makes it suitable for applications requiring high stability over wide temperature ranges. Consider the 0805 footprint constraints and the 25V rating to ensure compatibility with the system's electrical requirements and physical layout limitations.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with flexible terminations to enhance reliability in environments subject to mechanical stress. The series is engineered to prevent electrode cracking caused by board bending during operation or assembly, offering superior durability compared to standard rigid-termination MLCCs.

Replacement Considerations

Direct substitutes include KYOCERA AVX KGM21ACG1E392KU. Verify pinout compatibility and thermal characteristics before substitution.
