Fixed Inductors Procurement Notes

Verify the specific datasheet version before procurement, as specifications may vary between distributors. Confirm that the semi-shielded variant matches the system's EMI requirements. Ensure the operating temperature range meets the environmental conditions of the target application. Cross-reference the part number with official Taiyo Yuden documentation to avoid confusion with similar models.

Fixed Inductors Selection Notes

Select this component when a semi-shielded inductor is required to balance size and magnetic field containment. The 47 µH value suits moderate filtering needs in compact designs. Consider the 85 mA current rating against peak load requirements. The 1007 package size fits space-constrained PCB layouts. Verify compatibility with reflow soldering profiles for surface mount assembly.

Fixed Inductors Part Context

This part belongs to the LLQBA series of high-reliability inductors. It shares the 1007 (2518 metric) footprint with other variants like LB2518T470M but differs in shielding and core material. The series targets demanding environments requiring robust magnetic performance and thermal stability.

Fixed Inductors Replacement Considerations

LSQBA251818T471K is listed as a suggested alternate by Mouser. Verify electrical parameters and physical dimensions before substitution. Check if the alternative offers equivalent shielding and current ratings.
