Fixed Inductors Procurement Notes

Verify the ordering suffix 'HTS' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SMT reflow profiles. Confirm RoHS3 compliance status prior to integration into environmentally regulated assemblies. Cross-reference manufacturer part numbers with distributor codes to prevent procurement errors.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values under 10 nH. Consider the 140 mOhm DCR for power loss calculations in high-current paths. Evaluate the 540 mA rating against peak load requirements. The unshielded design may require layout considerations to minimize electromagnetic interference coupling with nearby traces.

Fixed Inductors Part Context

This inductor belongs to the 0402HM series of ceramic RF inductors manufactured by Delta Electronics/Components. The series utilizes drum core technology optimized for radio frequency performance. Components in this family are designed for use in passive and magnetic applications across consumer electronics, automotive, and industrial sectors.

Fixed Inductors Replacement Considerations

The 0402HM-9N1EGTS is a documented substitute variant within the same series. Verify that the EGTS suffix aligns with required packaging formats. Ensure electrical parameters including inductance, current rating, and DCR remain identical to maintain circuit functionality.
