Fixed Inductors Procurement Notes

Verify the complete part number including the suffix EKTS to ensure correct tolerance and packaging specifications. Confirm RoHS3 compliance status if required for specific regulatory environments. Check manufacturer datasheets for updated lead times and availability as supply chain conditions may vary. Ensure storage conditions align with MSL Level 1 requirements to maintain component integrity prior to assembly.

Fixed Inductors Selection Notes

Select this component when a very low inductance value near 7.3 nH is required for high-frequency applications. The 0402 footprint suits space-constrained designs. Consider the 570 mA current rating against circuit load requirements. The unshielded nature requires careful layout consideration to minimize electromagnetic interference coupling with nearby traces compared to shielded alternatives.

Fixed Inductors Part Context

This component belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic core wirewound technology optimized for high-frequency performance. Similar parts in the series include variants with different inductance values such as 0402HM-7N0EDTS, maintaining consistent package dimensions and mounting characteristics while varying electrical parameters.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 7.3 nH inductance, 0402 package, and similar current ratings. Verify that alternative components offer comparable self-resonant frequencies and Q values to maintain circuit performance. Cross-reference pinout and thermal characteristics to ensure compatibility with existing PCB layouts.
