Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your automated assembly equipment requirements. Confirm that the RoHS compliance status aligns with your manufacturing environmental standards. Check for any recent product change notifications or end-of-life announcements from Samsung Electro-Mechanics to ensure long-term supply stability for your production cycle.

Fixed Inductors Selection Notes

Select this component when a low inductance value near 4.7 nH is required for high-frequency circuit tuning. The 0402 package size is appropriate for space-constrained designs where standard larger footprints cannot fit. Ensure the 300 mA current rating meets the operational DC bias conditions of your application to prevent saturation. Consider the unshielded nature of the part regarding potential electromagnetic interference coupling in sensitive layouts.
