NFM41CC221U2A3L

Overview

The NFM41CC221U2A3L is a three-terminal feed-through capacitor from the Murata EMIFIL NFM41C series, designed for EMI suppression in signal lines. It features a capacitance of 220 pF with a tolerance of -20% to +50%. The component has a DC voltage rating of 100 V and a current rating of 300 mA. It utilizes an SMD/SMT termination type within a 1806 (4.5 mm x 1.6 mm x 1 mm) package. The device operates between -55°C and +125°C, holds AEC-Q200 qualification, and exhibits an insulation resistance of 10 GOhms.

Feature Summary

• Three-terminal feed-through architecture provides effective high-frequency noise attenuation for signal integrity.
• Surface-mount design facilitates automated assembly and compact circuit board integration.
• Automotive-grade reliability ensured through AEC-Q200 qualification standards.

Applications

• EMI suppression in automotive electronic control units
• Signal line filtering in industrial equipment
• Noise reduction in communication interface circuits

Procurement Notes

Verify the specific suffix U2A3L against official Murata documentation to confirm exact capacitance tolerance and terminal configuration. Confirm end-of-life status if sourcing from secondary markets, as availability may be limited. Ensure compatibility with peak reflow temperature profiles specified in the datasheet during manufacturing processes.

Selection Notes

Select this component when low parasitic inductance is critical for high-speed signal filtering. The 1806 footprint offers a balance between thermal performance and space constraints. Consider the -20% to +50% tolerance range for circuit design margins. Verify that the 300 mA current rating exceeds the maximum expected signal current to prevent performance degradation.

Part Context

This part belongs to the Murata NFM41C series of single-circuit feed-through capacitors. These components are engineered specifically for suppressing electromagnetic interference on signal lines rather than power lines. The series utilizes ceramic dielectric materials optimized for stable performance across wide temperature ranges and high frequencies.

Replacement Considerations
