Procurement Notes
Verify the manufacturer part number 742792064 against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified 0805 package dimensions and electrical characteristics. Check for compliance with RoHS and REACH standards as listed in the product datasheet. Ensure storage conditions maintain component integrity prior to assembly.
Selection Notes
Select this component when space-constrained designs require EMI filtering in automotive or digital applications. The 0805 footprint offers a balance between current handling and size. Consider the 75Ω impedance at 100MHz for target noise frequencies. Verify that the 300mA current rating meets circuit requirements without excessive thermal rise.
Part Context
This ferrite bead belongs to the WE-CBF series, designed specifically for SMD EMI suppression. The series is characterized by its ability to attenuate high-frequency noise while maintaining low DC resistance. It is suitable for protecting sensitive circuits from electromagnetic disturbances in modern electronic assemblies.
Replacement Considerations
No specific substitute part numbers are confirmed in the provided public documentation. Cross-referencing requires matching impedance, current rating, and package dimensions.
