Fixed Inductors Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm electrical parameters, as variations may exist within the series. Confirm RoHS3 compliance status directly from the datasheet before integration. Ensure the selected packaging format matches assembly line requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Fixed Inductors Selection Notes

Select this component when a 3.9 nH inductance is required in a minimal 0402 footprint. The 1.7 A rating supports higher current loads compared to standard variants. Consider the unshielded nature for layout sensitivity. Verify that the 10 GHz self-resonant frequency aligns with the target operating range. Compare DCR specifications against thermal constraints in the final application.

Fixed Inductors Part Context

This component belongs to the 0402HP series of fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values within the 0402 package size. These inductors are designed for surface mount technology and are commonly used in consumer electronics and telecommunications equipment requiring small form factors.

Fixed Inductors Replacement Considerations

The 0402HM-3N9EBTS is a similar 3.9 nH inductor but has a lower rated current of 750 mA and higher DC resistance of 70 mΩ. The 0402HC-3N9ECTS also offers 3.9 nH but differs in current rating and physical dimensions. Verify compatibility before substitution.
