Fixed Inductors Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm RoHS compliance status and tolerance class. Ensure that the ordered component matches the required inductance value and current rating specifications for the target application circuit design.

Fixed Inductors Selection Notes

Select this component based on its 2.4 µH inductance and 11.3 A current handling capability. Consider the 10.5 mΩ DC resistance for efficiency calculations. Verify that the physical dimensions fit the PCB land pattern requirements and that the operating temperature range meets the environmental conditions of the end product.

Fixed Inductors Part Context

This part belongs to the CDRH127 series of general-purpose power inductors. The series provides various inductance values ranging from 1.0 µH to 1,000 µH with different current ratings. The 'LDF' designation typically indicates specific manufacturing attributes such as lead-free plating or RoHS compliance within the Central Technologies portfolio.

Fixed Inductors Replacement Considerations

Direct substitutes include other CDRH127 series variants with matching electrical parameters. Cross-manufacturer equivalents should match the 12.3mm x 8.0mm footprint, 2.4 µH inductance, and similar current ratings while maintaining shielded construction.
