• Noise reduction in portable device power circuits

Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct voltage and tolerance specifications. Confirm that the required packaging format matches project needs, as availability varies between cut tape, reel, and Digi-Reel options. Cross-reference datasheet revisions to validate compliance requirements such as RoHS3 status before finalizing procurement orders.

Selection Notes

Select this component when a compact 0805 footprint is required for high-capacitance feedthrough filtering. Ensure the circuit operates within the 10 VDC limit and 4 A current rating. Consider the -40°C to +85°C operating range for environmental compatibility. Verify PCB pad layout compatibility with the three-terminal design to maximize grounding effectiveness and minimize electromagnetic interference.

Part Context

This component belongs to the Murata EMIFIL NFM21P series of three-terminal feedthrough capacitors. The series offers various capacitance values and voltage ratings within the same 0805 package dimensions. These components are engineered to replace traditional two-terminal capacitors by providing superior high-frequency performance through integrated ground terminals.

Replacement Considerations

Consult the official Murata NFM21PC series datasheet for direct substitutes with identical or adjusted electrical parameters. Verify pinout compatibility and physical dimensions before substituting with other manufacturers' three-terminal feedthrough capacitors.
