Fixed Inductors Procurement Notes

Verify that the ordering suffix matches the required tolerance and packaging format. Confirm RoHS3 compliance status for regulatory adherence. Check manufacturer lead times as standard delivery may extend up to 24 weeks. Ensure storage conditions align with MSL Level 1 requirements to maintain component integrity prior to assembly.

Fixed Inductors Selection Notes

Select this component when low inductance values are required in minimal space. Compare DCR and current ratings against circuit load requirements to prevent saturation. Consider the unshielded nature for layout sensitivity regarding magnetic interference. Validate self-resonant frequency limits against the target application bandwidth to ensure effective performance.

Fixed Inductors Part Context

This part belongs to the 0402HM series of wirewound chip inductors manufactured by Delta Electronics/Components. The series offers various inductance options within the 0402 package size, catering to applications requiring small form factors and reliable high-frequency characteristics. It complements other Delta inductor lines like the 0402HP and 0402HS series.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402HM series variants with identical electrical parameters but different tolerances or packaging. Cross-reference with Delta's 0402HS series for similar physical dimensions if higher current handling is needed, though electrical characteristics will differ.
