NFM41CC223R2A3L

Overview

The NFM41CC223R2A3L is a three-terminal feedthrough capacitor from the Murata EMIFIL NFM41 series. It features a capacitance of 0.022 µF with a tolerance of -20% to +50%. The device has a DC voltage rating of 100 V and a rated current of 300 mA. Its maximum DC resistance is 300 mΩ. The component operates within a temperature range of -55°C to +125°C. It utilizes an SMD surface mount package in the 1806 (4516 metric) dimension, measuring 4.50 mm in length, 1.60 mm in width, and 1.20 mm in height.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise suppression compared to standard two-terminal capacitors.
• Low equivalent series inductance design enables effective attenuation of electromagnetic interference in high-speed signal lines.
• Robust construction supports high current handling capabilities suitable for power line filtering applications.

Applications

• High-speed data interface noise suppression
• Power supply line filtering for sensitive electronics
• EMI reduction in automotive electronic control units

Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct capacitance tolerance and termination specifications. Confirm that the required operating temperature range aligns with the -55°C to +125°C specification. Ensure PCB layout accommodates the three-pad ground configuration inherent to the 1806 feedthrough package type for optimal performance.

Selection Notes

Select this component when high-frequency noise attenuation is critical in space-constrained designs. The 1806 footprint offers a balance between capacitance value and physical size. Consider the 300 mA current rating for power line applications. Verify compatibility with automated pick-and-place equipment due to the small surface mount form factor.

Part Context

This part belongs to the Murata EMIFIL NFM41 series of three-terminal feedthrough capacitors. These components are designed for EMI suppression in digital circuits. The series includes various capacitance values within the same 1806 package family, allowing designers to select appropriate filtering characteristics without changing the board footprint.

Replacement Considerations

Check Murata's official substitution lists for direct replacements. Equivalent parts from other manufacturers may require verification of impedance characteristics and thermal ratings.
