Fixed Inductors Procurement Notes

Verify the exact inductance value and tolerance against the schematic requirements, as the suffix indicates 10 µH. Confirm that the unshielded nature aligns with the system's electromagnetic compatibility strategy. Ensure the PCB footprint matches the 13.05 mm length and 11.50 mm height specifications. Check that the operating temperature limit of +85 C meets the environmental conditions of the final assembly.

Fixed Inductors Selection Notes

Select this component when a high-current, unshielded inductor is required for space-constrained designs. The 10 µH value suits moderate frequency switching applications. Consider the 8 A rating to ensure adequate margin for peak load currents. The non-standard package dimensions require careful placement on the layout to avoid mechanical interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the HDC450 series of Hi-Profile SMD Drum Core Inductors manufactured by HALO Electronics. The series offers various inductance values tailored for power electronics. The HDC450-100MTR specifically denotes the 10 µH variant within this lineup, distinguished by its unshielded drum core architecture and high current capacity compared to lower profile alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include HDC450-330MTR, HDC450-150MTR, and HDC450-471MTR, though these differ in inductance values. Cross-series replacements such as the HPC104N variants offer shielded alternatives but may have different current ratings and physical dimensions.
