NFM31HK223R1H3L

Overview

The Murata NFM31HK223R1H3L is a surface-mount feedthrough capacitor designed for electromagnetic interference suppression. It features a capacitance of 0.022 µF with a ±20% tolerance and a rated DC voltage of 50V. The component operates within a temperature range of -55°C to +125°C and carries AEC-Q200 qualification. It utilizes a 1206 (3216 Metric) package with three pads, measuring 3.20mm x 1.60mm x 1.50mm. Key electrical characteristics include a maximum DC resistance of 1.5 mΩ and a current rating of 6A.

Feature Summary

• Three-terminal feedthrough architecture providing effective EMI noise suppression in compact form factors
• High current handling capability suitable for power line filtering applications
• Automotive-grade reliability certified under the AEC-Q200 standard

Applications

• Power supply input filtering for automotive electronic control units
• EMI suppression on high-current data lines in industrial equipment
• Noise reduction in portable devices requiring robust power integrity

Procurement Notes

Verify the specific suffix against official Murata documentation to ensure correct capacitance and voltage ratings. Confirm that the AEC-Q200 qualification status aligns with project requirements. Check RoHS compliance details for environmental regulations. Ensure the 1206 footprint matches the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when high current capacity and low impedance are required for EMI filtering. The 50V rating suits moderate voltage systems, while the 6A rating supports significant load currents. Consider the 1206 size for space-constrained designs needing superior noise attenuation compared to standard capacitors. Evaluate thermal performance within the specified operating range.

Part Context

This part belongs to the Murata EMIFIL NFM31 series, which focuses on high-performance feedthrough capacitors. The series is engineered for demanding environments, offering stable performance across wide temperature ranges. It complements other components in signal conditioning and power management circuits by providing targeted noise filtration.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Generic replacements may not match the specific 6A current rating or 1.5 mΩ DC resistance. Verify package dimensions and terminal configurations to ensure mechanical compatibility without redesigning the PCB.
