74279218

Overview

The Würth Elektronik 74279218 is a surface-mount ferrite bead from the WE-CBF series, designed for high-frequency noise suppression in compact electronic assemblies. Housed in a 1206 (3216 Metric) package, this component provides an impedance of 600 Ω at 100 MHz with a maximum DC resistance of 100 mΩ and a current rating of 2 A. It operates within a temperature range of -55°C to +125°C and carries AEC-Q200 qualification, ensuring reliability for automotive applications.

Feature Summary

• AEC-Q200 qualified for automotive grade reliability
• High impedance performance at 100 MHz
• Compact 1206 surface-mount footprint

Applications

• Automotive electronics systems
• Data line filtering
• Power supply output filtering

Procurement Notes

Verify the specific datasheet version and manufacturer lot codes upon receipt. Confirm that the 1206 package dimensions align with your PCB land pattern requirements. Ensure the 2 A current rating meets the operational load of the target circuit to prevent saturation or excessive heating during normal use.

Selection Notes

Select this component when space constraints require a 1206 package but high attenuation is needed at 100 MHz. The 100 mΩ DCR minimizes voltage drop in power lines, while the 2 A rating supports moderate current loads. Consider thermal management if continuous operation near the maximum current limit is expected.

Part Context

This part belongs to the WE-CBF series of surface-mount ferrite beads. It complements other components in the Wurth portfolio by offering a standardized SMD form factor suitable for automated assembly processes in consumer, industrial, and automotive manufacturing environments.

Replacement Considerations

Check for direct substitutes with identical 1206 dimensions, 600 Ω impedance at 100 MHz, and 2 A current handling. Verify that any alternative also holds AEC-Q200 certification if used in automotive contexts.
