NFM18CC220U1C3D

Overview

The NFM18CC220U1C3D is a three-terminal feed-through capacitor from the Murata EMIFIL NFM18 series, designed for surface-mount applications. It features a capacitance of 22 pF with a tolerance of ±20% and a DC voltage rating of 16V. The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 300 mΩ. Packaged in a compact 0603 (1608 metric) footprint measuring 1.60mm x 0.80mm x 0.70mm, it is AEC-Q200 qualified and RoHS compliant.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency noise suppression compared to standard two-terminal capacitors.
• AEC-Q200 qualification ensures reliability and performance consistency for automotive electronic applications.
• Compact 0603 surface-mount package enables efficient space utilization on densely populated printed circuit boards.

Applications

• EMI filtering for signal lines in automotive electronic control units
• Noise suppression in portable communication devices
• Power line filtering for embedded systems

Procurement Notes

Verify the specific suffix 'U' against official Murata documentation to confirm the exact capacitance value and tolerance, as variations exist within the NFM18CC family. Ensure the source document explicitly lists this part number as active or obsolete, noting that some distributors may list similar parts like NFM18CC470U1C3D which are marked as end-of-life. Cross-reference the manufacturer part number directly rather than relying solely on distributor search aliases to avoid substitution errors.

Selection Notes

Select this component when high-frequency EMI attenuation is required in space-constrained designs. The three-terminal structure offers better parasitic inductance reduction than standard capacitors. Consider the 16V rating and 22pF value for signal line protection. Verify thermal requirements against the -55°C to +125°C operating range. Ensure PCB layout supports the 0603 footprint and three-pad configuration for optimal grounding.

Part Context

This component belongs to the Murata EMIFIL NFM18 series, a line of three-terminal feed-through capacitors engineered for effective electromagnetic interference suppression. The series utilizes a unique internal structure to minimize stray inductance, making it suitable for high-speed digital circuits. The NFM18CC variant specifically denotes the 0603 case size and ceramic construction, balancing performance with compactness for modern electronics.

Replacement Considerations

Public data indicates the TDK YFF18SC1H470MT0H0N as a listed substitute for related NFM18CC parts, though capacitance values differ. Verify direct pin-to-pin compatibility and electrical equivalence with official manufacturer cross-reference lists before replacement.
