NFM21CC220U1H3D

Overview

The Murata NFM21CC220U1H3D is a surface-mount feedthrough capacitor from the EMIFIL NFM21C series. It features a capacitance of 22 pF with a tolerance of +50%/-20%. The device has a DC voltage rating of 50V and operates within a temperature range of -55°C to +125°C. It utilizes a three-terminal architecture in an 0805 (2012 metric) package, measuring 2.0 mm in length, 1.25 mm in width, and 0.85 mm in height. The component includes a 0.6 mm grounding terminal and supports SMD/SMT installation.

Feature Summary

• Three-terminal feedthrough design for effective high-frequency noise suppression
• Compact 0805 surface-mount footprint suitable for space-constrained layouts
• Wide operating temperature range supporting industrial environments

Applications

• High-speed digital signal line filtering
• Power supply decoupling in compact modules
• EMI suppression in mobile communication devices

Procurement Notes

Verify the specific suffix 'U' against official Murata documentation to confirm the exact capacitance tolerance band, as suffixes define critical electrical variances. Ensure the selected package matches the required PCB land pattern dimensions. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a low-capacitance value is required for high-frequency attenuation in a small form factor. The 50V rating provides adequate margin for standard logic and power rails. Consider the three-terminal grounding capability for superior RF performance compared to standard two-terminal capacitors in sensitive circuit designs.

Part Context

This part belongs to the Murata EMIFIL NFM21C series of feedthrough capacitors. These components are engineered for EMI/RFI suppression in portable electronics and automotive applications. The series offers various capacitance values within the 0805 package to address different filtering requirements while maintaining a consistent physical profile.

Replacement Considerations

Direct substitutes include other NFM21C series variants such as NFM21CC471R1H3D or NFM21CC101U1H3D if capacitance adjustments are permissible. Verify that any replacement maintains the same 0805 footprint and 50V rating to ensure mechanical and electrical compatibility.
