Procurement Notes
Verify the manufacturer part number against official Delevan documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the product family. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the package type aligns with your automated placement equipment specifications.
Selection Notes
Select this component when a low-inductance coupled inductor is needed for high-current SMT designs. The 1 µH value and 2.95 A rating suit applications demanding minimal impedance with significant current capacity. Consider the 7.87 mm height profile for board space constraints. Verify thermal management requirements given the wide operating temperature range.
Part Context
This component belongs to the Delevan 4448/R series of coupled inductors. These parts are characterized by their toroidal geometry and molded construction, suitable for robust power electronics. The series provides various inductance values, with the 106M variant specifically offering 1 µH. It falls under the broader category of power inductors and chokes used in signal and power conditioning.
Replacement Considerations
Cross-reference with other Delevan 4448R variants for different inductance values. Verify pinout compatibility before substituting with generic coupled inductors. Ensure equivalent current ratings and DC resistance levels are met by alternative sources.
