HCB1050-121H

Fixed Inductors Overview

The Delta Electronics HCB1050-121H is a fixed surface-mount inductor with an inductance of 120 nH and a tolerance of ±20%. It features a DC resistance (DCR) of 0.55 mΩ and a rated current of 31 A, with a saturation current (Isat) of 46 A. The component operates within a temperature range of -40°C to 125°C and is tested at 100 kHz. Its non-standard package measures 7.00 mm in length and width, with a maximum height of 5.00 mm.

Fixed Inductors Feature Summary

• High-current capability with 31 A rated current and 46 A saturation threshold for robust power handling
• Low DC resistance of 0.55 mΩ to minimize conduction losses in power circuits
• Unshielded design suitable for applications where magnetic shielding is not required or managed externally

Fixed Inductors Applications

• Power supply output filtering
• DC-DC converter input/output stages
• Voltage regulator module (VRM) circuits

Fixed Inductors Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm electrical parameters, as variations exist within the HCB1050 series. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm availability status directly with authorized distributors, as lead times may vary based on production schedules.

Fixed Inductors Selection Notes

Select this component when a 120 nH inductance value is required with high current handling capabilities up to 31 A. The low DCR makes it suitable for efficiency-critical designs. Consider the unshielded nature for layout planning to manage potential electromagnetic interference. Ensure the PCB footprint matches the 7.00mm x 7.00mm x 5.00mm dimensions.
