HCB1175-121L

Fixed Inductors Overview

The HCB1175-121L is a fixed surface-mount inductor from the Delta Electronics HCB1175 series. It features an inductance of 120 nH with a tolerance of ±15%. The component has a DC resistance (DCR) of 0.245 mΩ, a rated current of 52 A, and a saturation current (Isat) of 76 A. It operates within a temperature range of -40°C to 125°C and is tested at 100 kHz. The non-standard package dimensions are 11.00mm x 7.20mm x 7.50mm.

Fixed Inductors Feature Summary

• High-current capability with a 52A rated current and 76A saturation threshold for power delivery applications
• Low DC resistance of 0.245 mΩ to minimize conduction losses
• Unshielded design suitable for high-power density environments

Fixed Inductors Applications

• Point-of-load (POL) voltage regulation modules
• Server and data center power distribution networks
• High-performance computing power supplies

Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet for final electrical tolerances and thermal characteristics before integration. Confirm that the non-standard footprint matches the target PCB land pattern. Ensure supply chain sources provide RoHS3 compliant units consistent with environmental regulations. Cross-reference the 52A rated current against actual operating thermal conditions to prevent derating issues during peak loads.

Fixed Inductors Selection Notes

Select this component when circuit designs require low inductance values under 120 nH combined with high current handling exceeding 50A. The unshielded construction may necessitate careful layout planning to manage electromagnetic interference in dense assemblies. Compare the 0.245 mΩ DCR against alternative packages to optimize efficiency requirements for specific load profiles.
