Fixed Inductors Procurement Notes

Verify the specific suffix 'W' against official Taiyo Yuden documentation to confirm parameter alignment, as suffixes often denote critical variations in tolerance or rating. Confirm availability status directly with the manufacturer or authorized distributors, as this component may be subject to discontinuation notices. Ensure that the ordering part number matches the exact electrical specifications required for the target application before procurement.

Fixed Inductors Selection Notes

Select this component when a low-inductance, unshielded RF solution is required in a minimal 0201 footprint. Consider the 500 mA current rating and 200 mOhm DCR limits for power handling requirements. Evaluate the 8 GHz self-resonant frequency to ensure it exceeds the operating frequency of the circuit. Compare against shielded alternatives if electromagnetic interference suppression is necessary for the specific design.

Fixed Inductors Part Context

This part belongs to the HKQ series of high-Q RF inductors from Taiyo Yuden. The series is characterized by its use of ferrite materials to achieve superior quality factors at radio frequencies. The 0201 package size represents one of the smallest form factors available for this type of component, catering to modern miniaturization trends in consumer electronics and mobile devices.
