74279211

Overview

The Würth Elektronik 74279211 is a single-line surface-mount ferrite bead from the WE-CBF series, designed for EMI suppression in signal lines. It features a 1206 (3216 metric) package with dimensions of 3.20mm length and 1.60mm width. The component provides an impedance of 90 ohms at 100 MHz and supports a maximum DC current of 300mA. Its maximum DC resistance is 300 milliohms, ensuring low insertion loss. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Feature Summary

AEC-Q200 qualified for automotive electronic applications
High-speed EMI suppression for signal line protection
Compact 1206 surface-mount footprint for space-constrained designs

Applications

Automotive electronics systems
General electronic equipment signal filtering
High-speed data line EMI suppression

Procurement Notes

Verify the specific ordering suffix to confirm exact impedance tolerance and packaging configuration. Confirm that the procurement channel sources directly from authorized distributors to ensure component authenticity. Check the latest product change notices for any manufacturing updates. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range during selection.

Selection Notes

Select this component when a compact SMT ferrite bead with automotive qualification is required for signal integrity. The 300mA current rating suits low-power signal lines rather than power rails. Compare impedance characteristics against target noise frequencies to ensure effective attenuation. Consider the 300mOhm DCR for minimal voltage drop impact on sensitive circuitry.

Part Context

This part belongs to the WE-CBF series of SMT EMI suppression ferrite beads by Würth Elektronik. The series offers various impedance values and current ratings in standard footprints. The 74279211 specifically targets applications requiring robust EMI filtering with automotive-grade reliability standards integrated into a small form factor.
