Overview
The Murata NFM21HC221R1H3D is a three-terminal feedthrough capacitor from the EMIFIL NFM21HC series. It features a capacitance of 220 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 50 VDC and a current rating of 700 mA. It utilizes an SMD/SMT termination type in a 0805 (2012 metric) package, measuring 2.00 mm in length, 1.25 mm in width, and 0.85 mm in height. The component operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- Provides low-pass EMI/RFI filtering capabilities through its feedthrough architecture.
- Features a three-terminal design for effective noise suppression in compact spaces.
- Includes a dedicated ground terminal to enhance shielding performance.
Applications
- Automotive electronic circuits requiring AEC-Q200 qualified components
- High-current signal line filtering applications
- Compact PCB designs utilizing 0805 footprints
Procurement Notes
Verify the specific suffix 'R1H3D' against official Murata documentation to confirm exact capacitance tolerance and termination specifications. Ensure the selected variant matches the required 700 mA current rating and 50 VDC voltage limit for the target circuit. Confirm package dimensions align with the 0805 footprint requirements.
Selection Notes
Select this component when high current handling up to 700 mA is required alongside EMI filtering in a small 0805 form factor. The AEC-Q200 qualification makes it suitable for automotive environments. Compare against the NFM21HC471R1H3D if higher capacitance is needed, noting the difference in current ratings and capacitance values.
Part Context
This part belongs to the Murata EMIFIL NFM21HC series of three-terminal filter capacitors. These components are designed for high-performance noise suppression in space-constrained applications. The series offers various capacitance values while maintaining consistent package dimensions and high current ratings suitable for demanding electronic systems.
Replacement Considerations
The NFM21HC471R1H3D is a related series member with different capacitance and current ratings. Verify electrical compatibility before substitution. No direct public substitute part numbers are confirmed for this specific model.
