Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact tolerance and temperature stability ratings. Ensure that the selected variant matches the required electrical parameters for the target RF application. Cross-reference the part number with authorized distributors to confirm availability and compliance with relevant environmental standards before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required for space-constrained RF designs. The 1008 footprint offers a balance between current handling and physical size. Consider the 180 MHz self-resonant frequency limit to ensure operation remains below the resonant point for effective inductive behavior in the intended frequency band.
