Fixed Inductors Procurement Notes

Verify the specific suffix R11J to confirm the 110nH inductance value and 5% tolerance. Ensure the procurement matches the standard terminal type and reel packaging format. Confirm that the AEC-Q200 qualification meets the target automotive application requirements. Check compatibility with the intended PCB mounting style and temperature range specifications.

Fixed Inductors Selection Notes

Select this component for space-constrained designs requiring precise RF inductance in automotive environments. The unshielded construction suits applications where magnetic interference is manageable. Consider the 300mA current rating and 0.61 Ohm DCR for power loss calculations. The 1.35GHz self-resonant frequency defines the upper operational limit for effective inductive behavior.

Fixed Inductors Part Context

This part belongs to the Bourns CW161009A series of RF inductors. The series utilizes a wirewound technique on a ceramic substrate to achieve stable performance. The 0603 case size allows for dense PCB layouts. The AEC-Q200 certification indicates compliance with automotive electronic component stress testing protocols.

Fixed Inductors Replacement Considerations

Direct substitutes include other 110nH ±5% SMD RF inductors in 0603 packages with similar current ratings. Verify that alternative parts meet the same AEC-Q200 automotive qualification if required. Ensure the replacement maintains the 1.35GHz self-resonant frequency characteristic.
