Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard SMT reflow profiles given the ceramic core construction. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference manufacturer part numbers with distributor codes to avoid substitution errors during procurement.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values near 9 nH are required for RF tuning. The 0402 footprint suits space-constrained designs. Evaluate the 540 mA current rating against peak load requirements. Consider the 140 mOhm DCR impact on power loss. Verify that the 6 GHz self-resonant frequency exceeds the operating frequency to ensure inductive behavior.

Fixed Inductors Part Context

This inductor belongs to the 0402HM series, designed for high-frequency performance in minimal footprints. It utilizes a wirewound technique on a ceramic drum core to achieve precise inductance values. The series targets applications demanding stability and low parasitic effects in compact electronic assemblies.

Fixed Inductors Replacement Considerations

Check for direct substitutes within the same series offering identical 8.7 nH values. Verify pinout and dimensional compatibility for existing PCB layouts. Ensure replacement parts meet the same thermal and current specifications.
