Overview
The Murata NFM21HC223R1H3D is a three-terminal feedthrough capacitor from the EMIFIL NFM21HC series. It features a capacitance of 0.022 µF with a DC voltage rating of 50 V and a tolerance of ±20%. Designed for surface mount installation, it utilizes an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 0.85 mm height. The component operates within a temperature range of -55°C to +125°C and carries AEC-Q200 qualification.
Feature Summary
- Three-terminal feedthrough architecture providing superior high-frequency noise suppression compared to standard two-terminal capacitors.
- AEC-Q200 qualified for automotive reliability standards.
- Low equivalent series inductance (ESL) design optimized for EMI/RFI filtering applications.
Applications
- Automotive electronic systems requiring robust electromagnetic interference filtering.
- High-speed digital circuits needing power line decoupling and noise reduction.
- Communication equipment utilizing surface-mount technology for compact form factors.
Procurement Notes
Verify the complete part number including suffixes to ensure correct capacitance, voltage, and termination specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference datasheet parameters against specific circuit design constraints to validate performance suitability.
Selection Notes
Select this component when high-frequency noise attenuation is critical in space-constrained designs. The 0805 footprint allows for dense PCB layouts while maintaining effective grounding through the third terminal. Ensure the operating voltage remains below the 50 V DC rating under all transient conditions.
Part Context
This component belongs to Murata's NFM21HC series, which specializes in three-terminal feedthrough capacitors for automotive and industrial applications. The series offers enhanced filtering performance over traditional SMD capacitors by minimizing parasitic inductance through its internal structure.
Replacement Considerations
Direct substitutes include NFM21CC223R1H3D and NFM21HC471R1H3D. Verify package compatibility and electrical ratings before substitution. Consult official Murata documentation for detailed cross-reference data.
