HCB1190-471L

Fixed Inductors Overview

The HCB1190-471L is an unshielded fixed inductor from the Delta Electronics HCB1190 series, designed for surface mount applications. It features a nominal inductance of 470 nH with a tolerance of ±15%, tested at 100 kHz. The component supports a rated current of 50 A and a saturation current (Isat) of 35 A. Its DC resistance (DCR) is specified at 0.31 mOhm. The unit measures 11.50 mm in length, 11.20 mm in width, and has a maximum height of 9.00 mm. It operates within a temperature range of -40°C to 125°C and is supplied in tape and reel packaging.

Fixed Inductors Feature Summary

• High current handling capability with a 50 A rated current and 35 A saturation threshold for robust power delivery.
• Low DC resistance of 0.31 mOhm minimizes conduction losses and thermal generation in high-current circuits.
• Unshielded design allows for flexible layout integration while maintaining a compact non-standard footprint.

Fixed Inductors Applications

• Power supply output filtering
• DC-DC converter input/output stages
• High-current signal chokes

Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with your circuit requirements. Confirm that the 50 A rated current and 35 A saturation current meet your system's peak load demands. Check the physical dimensions (11.50mm x 11.20mm x 9.00mm) for adequate PCB space. Ensure the supplier provides genuine Delta Electronics/Components products with valid RoHS3 compliance documentation. Review the tape and reel specifications for proper automated assembly integration.

Fixed Inductors Selection Notes

Select this component when high current capacity and low impedance are critical for efficiency. The 470 nH value suits applications requiring moderate filtering at switching frequencies around 100 kHz. Consider the unshielded nature if magnetic interference with nearby components is not a primary concern. Compare the 0.31 mOhm DCR against alternatives to minimize power loss. Ensure the surface mount package fits the available footprint and reflow soldering profile.

Fixed Inductors Part Context

This inductor belongs to the HCB1190 series, which offers various inductance values and current ratings.
