Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the selected variant matches the required inductance value and current ratings for your specific circuit design before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when designing circuits requiring low inductance values under 100 nH combined with high continuous current capacity. Ensure the PCB layout accommodates the thermal dissipation requirements associated with the 0.39 mΩ DCR at full load conditions. Verify that the saturation current exceeds the peak current demands of the application to prevent performance degradation.

Fixed Inductors Part Context

This part belongs to the HCB1050 series of high-current SMT power inductors manufactured by Delta Electronics/Components. The series is engineered for demanding power electronics applications where space constraints and high efficiency are critical. The HCB1050-900 specifically targets designs needing minimal inductance for fast transient response while maintaining stability under heavy loads.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 90 nH inductance, 37 A rated current, and 0.39 mΩ DCR specifications. Consider components from other manufacturers offering similar HCB1050 form factors if availability is constrained, ensuring pin compatibility and thermal characteristics align with the original design.
