Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0805 footprint matches the PCB layout requirements. Ensure the operating temperature range aligns with the final application environment. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when space constraints require an 0805 SMD ferrite bead with significant impedance at 100 MHz. It is suitable for applications requiring AEC-Q200 certification. Compare the 500 mA current rating against the circuit's maximum DC load to prevent saturation. Consider the 25% tolerance for impedance variation in sensitive filter designs.
Part Context
This component belongs to the WE-CBF series of surface-mount ferrite beads manufactured by Würth Elektronik. The series is designed for EMI suppression in various electronic applications. The 0805 package size offers a balance between current handling capability and board space efficiency. The product line includes multiple impedance values tailored for different frequency ranges.
Replacement Considerations
Consult the manufacturer's official documentation for verified substitute part numbers within the WE-CBF series or equivalent products from other manufacturers. Ensure any replacement matches the 0805 footprint, 600 Ohm impedance at 100 MHz, and 500 mA current rating.
