Fixed Inductors Procurement Notes

Verify the specific suffix 'LR' against official TDK documentation to confirm lead time and packaging specifications. Ensure the requested quantity aligns with standard reel or cut tape availability. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when space constraints require a low-profile 1.0 mm height inductor. The 10 µH value suits applications needing moderate energy storage with 2.3 A continuous current handling. Evaluate thermal management requirements given the 193.8 mΩ resistance. Confirm that the 100 kHz test frequency matches the target switching application for accurate inductance validation.

Fixed Inductors Part Context

This part belongs to the TDK SPM-LR series of shielded power inductors. The series utilizes metal powder cores for high saturation characteristics. The SPM5015T designation indicates a specific footprint size optimized for dense PCB routing. These components are designed for commercial and industrial power electronics requiring reliable magnetic shielding.

Fixed Inductors Replacement Considerations

Direct substitutes include other TDK SPM5015T variants with matching 10 µH values, such as SPM5015T-100M-CA, if packaging differences are acceptable. Verify equivalent current ratings and DCR specifications when considering cross-brand alternatives from manufacturers like Murata or Coilcraft.
