HCB1190-471L1

Fixed Inductors Overview

The HCB1190-471L1 is a fixed surface-mount inductor from Delta Electronics, designed for high-current applications. It features an inductance of 470 nH with a tolerance of ±15%. The component supports a current rating of 42 A and a saturation current (Isat) of 36 A. Its DC resistance (DCR) is 0.42 mOhm. The unit is unshielded and operates within a temperature range of -40°C to 125°C. Measuring 11.00mm x 7.20mm x 7.20mm, it utilizes a non-standard package suitable for board mounting.

Fixed Inductors Feature Summary

• High current handling capability with 42 A rating and 36 A saturation threshold
• Low DC resistance of 0.42 mOhm for efficient power delivery
• Unshielded design allowing flexible PCB layout integration
• Robust thermal performance across -40°C to 125°C operating range

Fixed Inductors Applications

• Power supply input/output filtering
• DC-DC converter energy storage
• Industrial automation power distribution
• Server and data center power management

Fixed Inductors Procurement Notes

Verify the specific suffix L1 against official Delta documentation to confirm mechanical dimensions and termination style. Ensure the procurement channel provides genuine components with traceable date codes. Cross-reference the 470 nH value and 0.42 mOhm DCR with the manufacturer's datasheet to prevent substitution errors during assembly.

Fixed Inductors Selection Notes

Select this component when high current capacity is required alongside low inductance values. The 470 nH specification suits high-frequency switching applications where minimal impedance is needed. Consider the unshielded nature for EMI-sensitive designs requiring careful placement. The 36 A saturation limit defines the maximum operational current before inductance drops significantly.

Fixed Inductors Part Context

This part belongs to the HCB1190 series of fixed inductors from Delta Electronics. The series offers various inductance options tailored for different power levels. The HCB1190-471L1 specifically targets high-power density applications requiring robust current handling in a compact surface-mount footprint.

Fixed Inductors Replacement Considerations

Direct substitutes include other Delta HCB1190 variants with matching electrical parameters. Verify that alternative parts maintain the same 470 nH inductance and 0.42 mOhm DCR. Ensure physical compatibility by checking the 11.00mm x 7.20mm x 7.20mm dimensions against the target PCB land pattern.
