Overview
The Murata NFM3DCC221R1H3L is a surface-mount feedthrough capacitor from the EMIFIL NFM3DC series. It features a capacitance of 220 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 50V and a current rating of 300 mA. It utilizes a three-terminal design in a 1205 (3212 metric) package, measuring 3.20mm x 1.25mm x 0.90mm. Operating temperatures range from -55°C to +125°C. The component meets AEC-Q200 automotive qualification standards and complies with RoHS3 regulations.
Feature Summary
- Three-terminal feedthrough architecture for effective high-frequency noise suppression
- Automotive-grade reliability certified under AEC-Q200 standards
- Surface-mount construction compatible with automated assembly processes
Applications
- High-speed digital signal line filtering
- Power supply noise reduction in electronic circuits
- EMI suppression in automotive electronic systems
Procurement Notes
Verify the specific suffix 'L' against official Murata documentation to confirm packaging configuration. Ensure the selected variant matches the required tape-and-reel specifications for your manufacturing equipment. Cross-reference the AEC-Q200 certification status if the application demands strict automotive compliance. Confirm that the 300 mA current rating aligns with the operational requirements of the target circuit design.
Selection Notes
Select this component when compact size and high-frequency performance are critical. The 1205 footprint offers a balance between capacitance density and board space efficiency. Consider the -20% to +50% tolerance range during circuit simulation to ensure stable operation across temperature variations. Verify that the 50V rating provides sufficient margin for the maximum expected voltage spikes in the application environment.
Part Context
This part belongs to the Murata EMIFIL NFM3DC series, which specializes in feedthrough capacitors for EMI suppression. The series is designed for surface-mount applications requiring robust noise filtering in small form factors. These components are widely used in consumer electronics and automotive modules where space constraints and signal integrity are paramount concerns for system designers.
Replacement Considerations
Consult official Murata substitution guides for direct equivalents within the NFM3DC family. Verify pinout compatibility and electrical parameters before integrating alternative parts. Ensure any substitute maintains the same three-terminal structure and thermal characteristics.
