Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official Delta Electronics documentation to ensure correct packaging and tolerance specifications. Confirm that the requested variant matches the required current rating and inductance value for your specific schematic requirements. Cross-reference manufacturer part numbers with distributor codes to prevent procurement errors due to naming variations or obsolete listings.

Fixed Inductors Selection Notes

Select this component when low inductance values near 9 nH are required for high-frequency operation. Ensure the 1.4 A current rating exceeds the maximum expected load current to prevent saturation. Consider the unshielded nature of the design regarding potential electromagnetic interference coupling in sensitive RF environments compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the 0402HP series, which focuses on high-performance small-form-factor inductors. The series utilizes ceramic cores to maintain stability across wide temperature ranges. It complements other variants in the lineup offering different inductance values while maintaining consistent physical dimensions and mounting characteristics for board layout flexibility.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402HP series parts such as 0402HP-9N5EHTS or 0402HP-100EHTS if slight inductance adjustments are permissible. Verify that any replacement maintains the same 1.4 A current rating and 80 mΩ DCR characteristics to ensure circuit performance consistency.
