Fixed Inductors Procurement Notes

This component is officially designated as End of Life by Samsung Electro-Mechanics. Procurement should be approached with caution due to limited availability and potential supply chain discontinuation. Verify final stock quantities and last-time-buy dates directly with authorized distributors before committing to orders. Replacement strategies must be prioritized given the obsolescence notice.

Fixed Inductors Selection Notes

Select this part only if legacy compatibility or specific 15 nH unshielded characteristics are required for existing designs. Due to its discontinued status, alternative sourcing carries significant risk. Engineers should evaluate equivalent performance parameters from active series, ensuring identical inductance, current rating, and physical dimensions to maintain board integrity and electrical stability.

Fixed Inductors Part Context

The CIH03Q15NJNC belongs to Samsung Electro-Mechanics' CIH series of chip inductors. This series is designed for high-frequency applications requiring small form factors.
