NFM21CC470U1H3D

Overview

The NFM21CC470U1H3D is a three-terminal feed-through capacitor from Murata Electronics, designed for surface-mount technology in the 0805 (2012 metric) package. It features a capacitance of 47 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component operates within a temperature range of -55°C to +125°C and has a rated current of 700 mA. Physical dimensions are 2 mm in length, 1.25 mm in width, and 0.85 mm in height.

Feature Summary

• Three-terminal architecture provides low parasitic inductance for effective high-frequency noise suppression.
• Feed-through design integrates filtering directly into the signal path for compact circuit layouts.
• Surface-mount construction supports automated assembly processes.

Applications

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

Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard reflow soldering profiles for the 0805 form factor. Cross-reference datasheet revisions to validate performance parameters before integration into final designs.

Selection Notes

Select this component when space-constrained designs require efficient high-frequency noise attenuation. The 0805 footprint offers a balance between capacitance density and board area. Consider the 50V rating and 700mA current handling for appropriate margin in target applications.

Part Context

This part belongs to the NFM21CC series of EMIFIL three-terminal filter capacitors. These components utilize Murata's proprietary ceramic technology to achieve superior high-frequency characteristics compared to standard two-terminal capacitors, making them suitable for demanding EMI/RFI environments.

Replacement Considerations

Consult official Murata substitution guides for equivalent parts within the NFM21C family. Verify that alternative candidates match the 47 pF capacitance, 50V rating, and 0805 package dimensions to ensure mechanical and electrical compatibility.
