Procurement Notes

Verify component status as this part number is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or check for active replacement parts such as 74279261. Ensure all procurement activities account for potential supply chain limitations associated with discontinued components.

Selection Notes

Select this component for applications requiring 68 Ohm impedance at 100 MHz in a 0603 footprint. Consider the 300 mA current rating and 300 mOhm DCR limits during circuit design. Verify compatibility with automated pick-and-place processes due to the reel packaging format typically used for this series.

Part Context

This ferrite bead belongs to the WE-CBF series, which offers various impedance values and current ratings in standard SMD packages. The series is engineered for effective electromagnetic interference suppression in space-constrained environments, supporting both general industrial and automotive-grade applications.

Replacement Considerations

Distributor data indicates 74279261 as a recommended substitute from Würth Elektronik. Verify electrical parameters and physical dimensions before implementation.
