Procurement Notes

Verify the specific datasheet version to confirm the exact inductance tolerance, as sources indicate both 10% and 20% variants exist for this part number. Ensure the selected component matches the required current rating and physical footprint for your PCB layout. Cross-reference the manufacturer's official documentation for any recent updates to the 1100R series specifications before finalizing procurement.

Selection Notes

Select the 11R102C when a low-inductance, high-current solution is required for through-hole designs. Its unshielded nature may require consideration for electromagnetic interference in sensitive layouts. Compare against shielded alternatives if magnetic field containment is critical. Verify that the 3 A current rating aligns with the peak load requirements of the target circuit application.

Part Context

This component belongs to the Murata 1100R series of radial lead power inductors. The series offers various inductance values optimized for different power management needs. The 11R102C specifically addresses applications requiring minimal inductance with high current handling capabilities in a compact axial-radial form factor.

Replacement Considerations

Consult Murata Power Solutions for direct cross-references within the 1100R series. Alternative manufacturers offering similar 1 µH radial inductors with comparable 3 A ratings should be evaluated for mechanical fit and electrical performance equivalence.
