Overview
The Murata NFM21HC224R1A3D is a three-terminal feedthrough capacitor in the EMIFIL NFM21HC series. It features a capacitance of 0.22 µF with a rated voltage of 10 V DC and a maximum current rating of 2 A. The component utilizes a 0805 (2012 metric) surface-mount package, measuring 2 mm in length, 1.25 mm in width, and 0.85 mm in height. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Three-terminal feedthrough architecture for high-frequency EMI suppression
- High current handling capability up to 2 A
- Automotive-grade reliability compliant with AEC-Q200
- Compact 0805 surface-mount footprint
Applications
- Automotive electronic circuit filtering
- Power line noise suppression in vehicles
- EMI reduction in compact electronic modules
Procurement Notes
Verify the specific suffix codes against official Murata documentation to ensure correct voltage and tolerance ratings. Confirm that the required current rating aligns with the 2 A specification. Check for RoHS compliance status if environmental regulations apply to the target assembly. Ensure the 0805 package dimensions fit the designated PCB layout constraints.
Selection Notes
Select this component when high-frequency noise attenuation is required on power lines carrying up to 2 A. The 0.22 µF value provides effective decoupling for specific frequency ranges. The 10 V rating suits low-voltage automotive systems. Consider the 0805 size for space-constrained designs requiring robust EMI performance without larger packages.
Part Context
This part belongs to the Murata EMIFIL NFM21HC series of feedthrough capacitors. These components are designed for high-current applications where traditional capacitors may fail due to thermal or electrical stress. The series offers a balance of small form factor and high performance for automotive and industrial environments.
Replacement Considerations
Consult official Murata substitution guides for compatible alternatives. Verify that any substitute matches the 0.22 µF capacitance, 10 V rating, 2 A current capacity, and 0805 package dimensions. Ensure equivalent AEC-Q200 qualification if automotive use is required.
