7427924

Overview

The Würth Elektronik 7427924 is a WE-CBF series SMD EMI suppression ferrite bead in an 1806 (4516 metric) package. It exhibits an impedance of 850 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 1.5 A and has a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High impedance performance at 100 MHz for effective noise suppression
• Robust current handling capability up to 1.5 A
• Wide operating temperature range suitable for harsh environments

Applications

• Automotive electronic circuit protection
• EMI suppression in high-speed signal lines
• Power supply input filtering
• Noise reduction in data communication interfaces

Procurement Notes

Verify the specific impedance value against project requirements, as datasheets may list variations such as 60 Ohms or 850 Ohms depending on the exact revision. Confirm AEC-Q200 certification status directly with the manufacturer. Ensure the 1806 package footprint matches the PCB design. Check for RoHS compliance documentation prior to final procurement approval.

Selection Notes

Select this component when high current capacity is required alongside significant attenuation at 100 MHz. The 1806 package offers a balance between size and power handling. Consider the low DC resistance to minimize voltage drop in power paths. Verify thermal management capabilities given the 1.5 A rating and operating temperature limits.
