Procurement Notes
Verify the complete part number including suffixes against official Murata documentation to ensure correct capacitance, voltage, and termination specifications. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents prior to procurement. Ensure storage conditions align with moisture sensitivity level requirements specified in the product guidelines.
Selection Notes
Select this component when high capacitance density is required in an 0805 footprint. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Evaluate the 4 A current rating and 500 mΩ resistance against circuit load requirements. Consider the -40°C to +85°C operating range for environmental compatibility.
Part Context
This component belongs to the Murata EMIFIL NFM21P series of three-terminal feedthrough capacitors. The series is engineered for EMI/RFI noise suppression in space-constrained applications. The NFM21PC variant specifically denotes the 16 V DC rating and 1 µF capacitance value within the broader family of surface mount filter capacitors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Murata's official cross-reference tools or distributor databases for verified equivalents based on specific electrical and mechanical constraints.
