Procurement Notes

Verify the specific manufacturer part number against official Murata documentation to ensure accuracy, as distributor listings may contain variations or obsolete references. Confirm that the required inductance value and current ratings align with the design specifications before procurement. Check for any recent lifecycle status changes or recommended replacements directly from the manufacturer's official channels to avoid sourcing issues.

Selection Notes

Select this component when a high-current, unshielded through-hole inductor is required for power applications. The 680 µH value and 1.12 A rating make it suitable for moderate power filtering tasks. Ensure the PCB footprint accommodates the 16.80 mm diameter and 21.30 mm height constraints. Consider the lack of shielding if electromagnetic interference sensitivity is a critical design factor.

Part Context

This inductor belongs to the broader category of fixed power inductors manufactured by Murata Power Solutions. It utilizes a ferrite core material typical for such applications. The radial lead configuration distinguishes it from surface-mount alternatives, providing mechanical stability for higher current handling in industrial and commercial power electronics assemblies.

Replacement Considerations

Cross-reference with other 680 µH unshielded radial inductors offering similar current ratings. Verify pin spacing and dimensional compatibility before substituting. Consult official Murata databases for direct equivalents or updated series recommendations.
