Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as specified in official documentation. Check lead time availability as distribution may vary by region. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.
Selection Notes
Select this model for applications requiring 120 µH inductance with 1.3 A current handling. Compare DCR values against thermal constraints. Verify footprint compatibility with existing PCB layout. Consider saturation characteristics under peak load conditions to prevent performance degradation.
Part Context
This component belongs to the DS126C2 series of fixed power inductors designed for compact power supply designs. It complements other variants in the lineup offering different inductance values while maintaining consistent physical dimensions and shielding technology for standardized integration across multiple product lines.
Replacement Considerations
Consult official substitution lists for equivalent components with matching electrical parameters. Verify pinout compatibility before replacing. Ensure new parts meet identical thermal and current ratings.
