HCB1050-101

Fixed Inductors Overview

The HCB1050-101 is a fixed surface-mount inductor from the Delta Electronics HCB1050 series. It features an inductance of 100 nH with a ±20% tolerance, tested at 100 kHz. The component supports a rated current of 37 A and a saturation current (Isat) of 48 A. Its DC resistance (DCR) is 0.39 mΩ. The unshielded design measures 10.0 mm x 10.0 mm with a maximum height of 6.0 mm. It operates within a temperature range of -40°C to +125°C.

Fixed Inductors Feature Summary

• High-current capability with 37 A rated and 48 A saturation limits for power delivery applications
• Low DC resistance of 0.39 mΩ to minimize conduction losses
• Unshielded construction suitable for designs where magnetic shielding is not required or can be managed externally
• Surface mount package optimized for automated PCB assembly processes

Fixed Inductors Applications

• Power delivery networks in cloud computing equipment
• Current sensing circuits in portable devices
• Input/output filtering in automotive electronics
• Power stages in IoT hardware modules

Fixed Inductors Procurement Notes

Verify the specific suffix code on the datasheet, as Delta often uses alphanumeric codes to denote packaging variations or tape-and-reel specifications. Confirm that the manufacturer has not discontinued this specific variant, as availability may vary by region. Ensure the ordering quantity matches the standard reel size defined in the official documentation to avoid handling issues during assembly.

Fixed Inductors Selection Notes

Select this component when a 100 nH value is required with high current handling exceeding 37 A. Compare the 0.39 mΩ DCR against alternative inductors to ensure thermal performance meets system constraints. Verify that the unshielded nature does not cause interference with nearby sensitive components. Check footprint compatibility with the 10x10 mm mechanical dimensions before finalizing the design.

Fixed Inductors Part Context

This part belongs to the HCB1050 series of fixed inductors manufactured by Delta Electronics/Components. The series is designed for passive and magnetic component applications in portable devices, cloud computing, and automotive sectors. The HCB1050 designation indicates the physical case size family, while the suffix specifies the electrical characteristics.

Fixed Inductors Replacement Considerations

FP0705R1-R07-R by Eaton is listed as a similar substitute. Verify that the replacement maintains equivalent saturation current and DCR values. Ensure the physical footprint and pinout are compatible with the existing PCB layout.
