Fixed Inductors Applications

• Cloud computing equipment power distribution
• Automotive electronic systems
• IoT device power management

Fixed Inductors Procurement Notes

Verify the specific suffix 'L1' against official Delta documentation to confirm exact physical dimensions and pin configuration, as variations exist within the HCB1190 series. Ensure the procurement channel provides valid RoHS3 compliance certificates. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar models like HCB1175 or other HCB1190 variants that differ in current ratings or inductance values.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-current solution is required for surface mount assembly. The 380 nH value is appropriate for high-frequency switching applications where minimal impedance is critical. Consider the 28 A saturation limit carefully; if the application peak current exceeds this threshold, a higher-rated variant such as the HCB1190-321L may be necessary. The unshielded nature requires attention to PCB layout to manage electromagnetic emissions.

Fixed Inductors Part Context

This part belongs to the HCB1190 series of high-current SMT power inductors manufactured by Delta Electronics/Components. The series offers various inductance values ranging from 0.22 µH to 0.55 µH, catering to different power supply requirements. The HCB1190-381L1 specifically targets applications needing robust current handling with a compact footprint, fitting into the broader portfolio of passive and magnetic solutions for portable devices and cloud infrastructure.

Fixed Inductors Replacement Considerations

The HCB1190-321L is a confirmed substitute offering higher current capacity (50 A rated, 35 A Isat) with lower inductance (320 nH). Verify compatibility regarding saturation current and DCR specifications before substitution.
