Overview
The Würth Elektronik 74279206 is an SMD EMI suppression ferrite bead from the WE-CBF series, housed in a 0805 (2012 metric) package. It provides an impedance of 30 Ω at 100 MHz with a rated current of 3 A and a maximum DC resistance of 25 mΩ. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Provides electromagnetic interference suppression through high impedance characteristics
- Designed for surface mount assembly in compact electronic circuits
- Qualified for automotive applications under AEC-Q200 standards
Applications
- EMI suppression in digital signal lines
- Power line filtering in automotive electronics
- Noise reduction in portable device power supplies
Procurement Notes
Verify the exact impedance value and current rating against the official manufacturer datasheet before integration. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure the supplier provides documentation confirming AEC-Q200 compliance if used in automotive contexts. Check for RoHS certification status to meet environmental regulations.
Selection Notes
Select this component when space constraints require an 0805 footprint but higher current handling than standard beads allows. The 3A rating suits moderate power lines, while the 30Ω impedance targets specific noise frequencies around 100MHz. Consider thermal management capabilities given the low DC resistance and operating temperature range up to 125°C.
Part Context
This part belongs to the WE-CBF series of surface mount ferrite beads manufactured by Würth Elektronik. The series focuses on providing reliable EMI suppression solutions for modern electronic devices requiring compact form factors and robust performance under varying thermal conditions.
Replacement Considerations
Consult official Wurth Elektronik documentation for direct cross-references. Verify that any substitute matches the 0805 package, 30Ω impedance at 100MHz, and 3A current rating. Ensure equivalent AEC-Q200 qualification if automotive use is required.
