Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm RoHS compliance and lead-free status as indicated in manufacturer documentation. Ensure the requested quantity aligns with standard factory pack quantities to avoid partial reel issues. Confirm that the supplier provides original manufacturer traceability and valid certification documents upon request.

Fixed Inductors Selection Notes

Select this component when the application requires a very low inductance value combined with extremely high current handling capabilities. The shielded design is critical for systems sensitive to magnetic field leakage. Evaluate thermal performance under full load conditions to ensure the 60 A rating remains within safe operating limits for the specific PCB layout.

Fixed Inductors Part Context

This part belongs to the SPB series of power bead inductors from Bourns. These components are engineered for high-efficiency power conversion systems where space constraints and current density are primary design drivers. The series offers various inductance options to suit different switching frequencies and ripple current requirements.

Fixed Inductors Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute matches the 120 nH nominal value, 60 A current rating, and 10x6.2x12 mm footprint dimensions to ensure mechanical and electrical compatibility.
