Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan Inc. and generic Delevan branding. Confirm RoHS compliance status directly with the supplier, as documentation varies across distributors. Ensure the ordering suffix matches the required reel quantity specifications for your production line.

Selection Notes

Select this component when a 12 µH inductance value is required for unshielded RF environments. Consider the 160 mA current rating against peak load requirements. The 1008 (2525 metric) package dimensions must fit the designated footprint on the target printed circuit board layout.

Part Context

This part belongs to the 103/R series of fixed inductors manufactured by API Delevan Inc.
