HCB1380-321H1

Fixed Inductors Overview

The HCB1380-321H1 is a fixed unshielded power inductor from the Delta Electronics HCB1380 series. It features an inductance of 320 nH with a tolerance of ±15%. The component supports a rated current of 35 A and a saturation current (Isat) of 216 A, with a DC resistance (DCR) of 0.53 mΩ. Designed for surface mount installation, it operates within a temperature range of -40°C to 125°C. The physical dimensions are non-standard, typically measuring approximately 11.00mm in length and 7.20mm in width.

Fixed Inductors Feature Summary

• High current handling capability with a saturation rating of 216 A
• Low DC resistance of 0.53 mΩ for efficient power transmission
• Unshielded design suitable for applications where magnetic shielding is not required
• RoHS compliant construction meeting environmental standards

Fixed Inductors Applications

• Power supply output filtering
• DC-DC converter input/output stages
• High-current point-of-load regulation circuits

Fixed Inductors Procurement Notes

Verify the exact mechanical footprint against your PCB layout, as the package is listed as non-standard. Confirm that the 35 A rated current and 216 A saturation current meet your specific thermal and load requirements. Ensure the unshielded nature does not interfere with nearby sensitive components or traces due to potential magnetic field emission.

Fixed Inductors Selection Notes

Select this component when high current capacity and low impedance are critical. The 320 nH value is suitable for high-frequency switching applications requiring minimal inductive reactance. Compare the 0.53 mΩ DCR against alternative inductors to ensure optimal efficiency. Consider the unshielded design implications for electromagnetic interference (EMI) management in dense circuit layouts.

Fixed Inductors Part Context

This part belongs to the Delta Electronics HCB1380 series of fixed power inductors. The series offers various inductance values tailored for different current requirements. The HCB1380-321H1 specifically targets high-power density applications where low resistance and high saturation currents are necessary to maintain performance under heavy loads.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts from the Delta HCB1380 series with similar electrical characteristics, such as the HCB1380-361H1 or HCB1380-441H1, provided their inductance and current ratings align with the design needs. Verify compatibility with existing footprints before substitution.
