Fixed Inductors Procurement Notes

Verify the specific suffix 'H' or absence thereof against official datasheets, as variations may exist within the HCB1175 series. Confirm RoHS3 compliance status directly with the manufacturer. Ensure packaging quantities match project requirements, as standard reels may vary. Cross-reference mechanical dimensions carefully to guarantee compatibility with existing PCB footprints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when low inductance and high current capacity are required for synchronous buck converters. The 180 nH value suits high-frequency switching applications. Evaluate thermal performance under full load conditions given the 48 A rating. Compare DCR values against alternative models in the HCB1175 family to optimize efficiency. Ensure the non-standard footprint aligns with automated assembly capabilities.

Fixed Inductors Part Context

This part belongs to the HCB1175 series of fixed inductors manufactured by Delta Electronics/Components. The series targets high-power density applications in computing and telecommunications. Components in this line typically offer robust current handling and compact form factors. The HCB1175-181 specifically provides 180 nH inductance, distinguishing it from other variants like the HCB1175-121L or HCB1175-361L which differ in inductance and current ratings.

Fixed Inductors Replacement Considerations

Direct substitutes include other HCB1175 series variants such as HCB1175-121L or HCB1175-361L if inductance adjustments are permissible. Verify that any replacement maintains the same current rating and physical dimensions. Check for equivalent DCR and saturation characteristics to ensure circuit stability remains unaffected during substitution.
