Fixed Inductors Procurement Notes

Verify the specific ordering suffix and tape/reel specifications against the manufacturer's latest datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the recommended alternate part numbers are evaluated if this specific model is unavailable or discontinued in your region.

Fixed Inductors Selection Notes

Select this component when a compact semi-shielded inductor is required for moderate-power applications. The 1.5 A rating suits designs needing efficient magnetic shielding without full enclosure losses. Compare saturation current limits against peak load requirements to ensure stable operation under transient conditions.

Fixed Inductors Part Context

This part replaces the previous CB2518T1R0M designation within the Taiyo Yuden portfolio. It belongs to the LLQN series of high-current wound inductors. The 1007 package size allows for dense mounting on printed circuit boards while maintaining thermal performance.
