Fixed Inductors Procurement Notes

Verify the specific ordering suffix EHTS against manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required moisture sensitivity level and RoHS compliance status for the target assembly process. Cross-reference the full part number with official distributor catalogs to confirm active status and availability constraints.

Fixed Inductors Selection Notes

Select this component when a 39 nH inductance value is required in a 0402 package with a 450 mA current rating. Consider the 430 mΩ DCR impact on power loss and the 2.6 GHz self-resonant frequency limit for RF applications. Evaluate thermal management requirements given the -40°C to 125°C operating range and unshielded design characteristics.

Fixed Inductors Part Context

This part belongs to the 0402HP series of high-power fixed inductors from Delta Electronics/Components. The series utilizes wirewound technology with ceramic cores to provide stable inductance in small surface-mount packages. The HP designation indicates specific performance characteristics tailored for high-current and high-frequency applications within the 0402 form factor.

Fixed Inductors Replacement Considerations

Consult official Delta Electronics/Components documentation for direct cross-reference part numbers. Verify that any substitute maintains identical electrical parameters including 39 nH inductance, 450 mA rating, and 0402 dimensions.
