Fixed Inductors Procurement Notes

Verify the specific suffix 'HTS' against official Delta Electronics documentation to confirm tape-and-reel packaging and lead-free status. Ensure the requested quantity aligns with manufacturer standard packaging requirements. Cross-reference the DigiKey part number 2035-1481-2-ND for accurate sourcing channels. Confirm RoHS3 compliance if required by project specifications. Validate that the 570 mA current rating meets the application's peak load demands before ordering.

Fixed Inductors Selection Notes

Select this component when a precise 7.3 nH inductance is required in a minimal 0402 footprint. Consider the 570 mA current rating for low-power RF or signal paths. The unshielded design may require layout considerations to minimize electromagnetic interference with nearby traces. Verify self-resonant frequency limits if operating near GHz ranges. Compare Q-factor specifications at target frequencies against alternative series parts like the 0402HM-7N0ECTS for optimal circuit efficiency.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and drum core wirewound technology. Other variants in the series include different inductance values such as 7 nH and 4.3 nH, sharing similar physical dimensions and mounting characteristics. The series is designed for general-purpose surface-mount applications requiring small form factors.

Fixed Inductors Replacement Considerations

The 0402HM-7N0ECTS is a documented substitute within the same series offering 7 nH inductance. Both components share the 0402 package and ceramic drum core construction. Verify that the slight inductance difference and identical current ratings suit the specific circuit requirements before substitution.
