Procurement Notes

Verify end-of-life status before finalizing designs, as this component may be obsolete or subject to discontinuation by the manufacturer. Confirm availability through authorized distributors and check for valid replacement part numbers if production continuity is required. Ensure RoHS compliance matches project specifications.

Selection Notes

Select based on impedance requirements at the target frequency and current handling capabilities. The 0402 package limits physical size but requires careful PCB layout for thermal management. Verify that the DC resistance does not cause unacceptable voltage drop in the specific circuit application.

Part Context

This component belongs to the KEMET Z-SMS series of ferrite beads, which are widely used for electromagnetic interference suppression in electronic circuits. The series offers various impedance values and current ratings in standard surface mount packages to support diverse design needs.
