Fixed Inductors Procurement Notes

Verify the specific suffix 'K' corresponds to the required ±10% tolerance during procurement. Confirm that the 575 mA rated current and 300 mΩ DC resistance meet the thermal and electrical requirements of the target circuit design. Ensure the 1812 package dimensions align with the PCB footprint specifications.

Fixed Inductors Selection Notes

Select this component when a compact 390 nH inductance value is required for high-frequency applications. The 1812 package offers a balance between current handling capability and board space efficiency. Consider the 575 mA saturation limit to ensure adequate headroom for peak current demands in the application.

Fixed Inductors Part Context

This part belongs to the CTMC1812SF series of shielded or unshielded drum core wire-wound inductors manufactured by Central Technologies. The series covers various inductance values suitable for general electronic applications, providing standardized footprints for easy integration into modern printed circuit boards.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 390 nH inductance, 1812 package size, and similar current ratings. Verify compatibility with existing PCB land patterns and thermal dissipation characteristics before substitution.
