- Signal line filtering in electronic circuits
Procurement Notes
Verify the specific ordering suffix against official Murata documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes. Cross-reference datasheet parameters with design specifications to validate thermal and electrical performance under operational conditions.
Selection Notes
Select this component when compact signal line filtering is required in space-constrained designs. The 0805 footprint accommodates standard surface mount assembly processes. Ensure the 1 A current rating meets circuit load requirements and that the 50 V DC rating exceeds maximum operating voltages. Verify compatibility with reflow soldering profiles specified for the NFM21C series.
Part Context
This part belongs to the Murata EMIFIL NFM21C series of single-circuit feedthrough capacitors. These components are engineered specifically for suppressing electromagnetic interference on signal lines. The series offers various capacitance values within the same 0805 form factor, allowing designers to maintain consistent board layouts while adjusting filter characteristics.
Replacement Considerations
Consult official Murata substitution guides for verified alternatives. No public substitute part numbers are confirmed in the provided source material.
