Fixed Inductors Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official datasheet to confirm it denotes the correct tolerance or packaging variant, as suffixes can indicate differences in lead finish or reel specifications. Ensure the ordering quantity matches the manufacturer's standard packing unit, which may differ from the requested amount. Confirm RoHS3 compliance status if required by your assembly process. Cross-reference the DigiKey part number 2035-1033-2-ND for accurate availability and packaging details.

Fixed Inductors Selection Notes

Select this component when high current handling and low impedance are critical for efficiency. The 320 nH value is suitable for high-frequency switching applications requiring minimal energy storage but significant current capacity. Compare the 50 A saturation limit against peak load currents to prevent performance degradation. Consider the unshielded nature for PCB layout planning to manage electromagnetic interference with nearby sensitive components.

Fixed Inductors Part Context

This inductor belongs to the HCB1380 series, designed for high-power density applications. It shares the same footprint dimensions with other variants in the series, such as the HCB1380-441L and HCB1380-361L, allowing for potential design flexibility across different inductance values. The series is characterized by its ability to handle substantial currents while maintaining a compact profile suitable for modern surface-mount assembly techniques.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include HCB1380-441L and HCB1380-361L, though these have different inductance values. Verify that any replacement maintains the required 68 A rated current and 0.165 mOhm DCR characteristics. Ensure the physical footprint remains compatible with existing PCB pads.
