Overview
The Würth Elektronik 74279201 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0805 (2012 metric) package. It provides an impedance of 32 Ω at 100 MHz with a rated DC current of 500 mA. The component features a maximum DC resistance of 60 mΩ and operates within a temperature range of -55°C to +125°C. It is certified to AEC-Q200 standards for automotive reliability.
Feature Summary
- Provides electromagnetic interference suppression through high-frequency impedance characteristics
- Designed for surface-mount assembly in compact electronic layouts
- Complies with AEC-Q200 qualification standards for automotive applications
Applications
- Automotive electronics circuits requiring EMI filtering
- Digital signal line noise suppression
- Power supply output filtering
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before procurement, as distributor listings may contain discrepancies. Confirm the package type is 0805 and that AEC-Q200 certification is required for your application. Ensure the supplier provides genuine Wurth Elektronik components with traceable documentation.
Selection Notes
Select this component when a low-profile SMD ferrite bead is needed for moderate current applications up to 500 mA. The 32 Ω impedance at 100 MHz suits general digital noise suppression. Consider the 0805 footprint for space-constrained boards. Verify thermal management requirements given the 60 mΩ DC resistance under load conditions.
Part Context
This part belongs to the WE-CBF series of surface-mount ferrite beads manufactured by Würth Elektronik. The series offers various impedance and current ratings in standard packages like 0805 and 0603. These components are designed to suppress high-frequency noise in data lines and power supplies, particularly in automotive and industrial environments where reliability is critical.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires consulting manufacturer compatibility lists or equivalent electrical specifications from other suppliers.
