Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and specific packaging requirements directly with the supplier or authorized distributor prior to ordering.
Selection Notes
Select this component when a Class 1 C0G dielectric is required for precise capacitance stability over varying temperatures. The 1206 package provides a balance between capacitance value and physical footprint. Ensure the application environment does not exceed the specified maximum operating temperature of 125°C.
Part Context
This component belongs to the Knowles Syfer high-reliability MLCC series. These capacitors are engineered for demanding environments where standard commercial-grade components may fail due to mechanical strain or thermal cycling. The product line emphasizes durability and consistent electrical performance in critical systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's catalog for equivalent parts with matching voltage, capacitance, and termination specifications.
