Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 1206 package dimensions align with your PCB footprint requirements. Ensure the 3A current rating meets your circuit's operational demands under all thermal conditions. Cross-reference the part number to avoid confusion with similar impedance values in the same series.
Selection Notes
Select this component when a 30 Ohm impedance at 100 MHz is required for EMI filtering. The 3A current rating makes it suitable for moderate power applications. The 1206 package offers a balance between size and performance. Consider the 40 mOhm DC resistance impact on voltage drop in your design. Verify AEC-Q200 certification if the application involves automotive environments.
Part Context
This ferrite bead belongs to the WE-CBF series, which focuses on SMT EMI suppression solutions. The series provides various impedance and current ratings to suit different filtering needs. Würth Elektronik designs these components for reliable performance in demanding electronic environments, offering standardized packaging for automated assembly processes.
Replacement Considerations
Check for direct substitutes within the WE-CBF series with matching 30 Ohm impedance and 3A current rating. Verify package compatibility and electrical parameters before substitution. Consult official Wurth Elektronik documentation for approved alternative part numbers.
