Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm manufacturing origin and specific lot traceability requirements before procurement. Ensure ordering quantities align with standard packaging configurations provided by the manufacturer. Validate that the component meets all environmental and export control classifications required for your specific deployment region.

Selection Notes

Select this component when high inductance values are required in a compact axial form factor. Consider the low maximum DC current rating of 33 mA during circuit design to prevent saturation or thermal issues. Verify that the 43 Ohm DC resistance is acceptable for the target application's power loss constraints. Ensure the physical dimensions fit within the available PCB real estate.
