HCB1190-381L

Fixed Inductors Overview

The HCB1190-381L is a fixed surface-mount power inductor from Delta Electronics, designed for high-current applications. It features an inductance of 380 nH with a tolerance of ±15%. The component supports a rated current of 50 A and a saturation current (Isat) of 28 A. Its DC resistance (DCR) is specified at 0.31 milliohms. The device operates within a temperature range of -40°C to 125°C and utilizes a non-shielded construction. Physical dimensions are approximately 11.2 mm x 11.2 mm x 9.0 mm.

Fixed Inductors Feature Summary

• High current handling capability with a rated current of 50 A
• Low DC resistance of 0.31 milliohms for efficient power delivery
• Compact surface-mount design suitable for space-constrained layouts

Fixed Inductors Applications

• Portable devices
• Cloud computing equipment
• Automotive systems
• IoT infrastructure

Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'L' against the manufacturer's official documentation to ensure correct pinout and mechanical specifications. Confirm that the 50 A rated current aligns with your system's thermal management capabilities. Check RoHS3 compliance status if required by your assembly standards. Ensure the non-shielded nature does not interfere with nearby sensitive circuitry during layout.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 380 nH is required for high-frequency switching applications. The 50 A rating makes it suitable for primary-side or output filtering in high-power converters. Consider the physical height of 9.0 mm for board clearance constraints. Evaluate the saturation current of 28 A against peak load conditions to prevent performance degradation.

Fixed Inductors Part Context

This part belongs to the HCB1190 series of high-current SMT power inductors from Delta Electronics. The series is engineered for passive and magnetic solutions in modern electronics. It complements other variants like the HCB1175 and HCB1075N, offering different inductance and current profiles for diverse power management needs.

Fixed Inductors Replacement Considerations

Direct substitutes include other Delta HCB1190 series variants such as HCB1190-321L or HCB1190-471L1, provided the inductance and current ratings meet the design requirements. Cross-referencing with generic high-current inductors requires matching the 11.2x11.2x9.0 mm footprint and 0.31 mΩ DCR.
