Procurement Notes
Verify the manufacturer part number HM66-60120LFTR13 against official TT Electronics documentation to confirm availability and specifications. Ensure compatibility with surface-mount reflow soldering processes. Check for any specific handling requirements related to the reel packaging format. Confirm that the 12 uH inductance and 1.55 A current rating meet the target circuit design requirements before procurement.
Selection Notes
Select this component when a shielded SMD power inductor with 12 uH nominal inductance is required. Consider the 70 mOhm DC resistance and 1.55 A current rating for efficiency and thermal management. The HM66 series offers a compact form factor suitable for space-constrained PCB layouts. Verify that the wirewound construction aligns with the application's frequency and stability needs.
Part Context
The HM66-60120LFTR13 belongs to the HM66 series of power inductors produced by TT Electronics/BI Magnetics. This series is characterized by shielded designs and wirewound cores, targeting reliable performance in surface-mount applications. The component is categorized under fixed inductors within the broader inductors, coils, and chokes product family.
Replacement Considerations
Cross-reference with other HM66 series variants or equivalent shielded SMD power inductors from TT Electronics if stock is unavailable. Ensure substitute components match the 12 uH inductance, 1.55 A current rating, and 70 mOhm DC resistance specifications.
