Fixed Inductors Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for some variants. Confirm lead content and REACH restrictions before integration. Check manufacturing lead times due to potential stock shortages. Ensure the specific suffix matches required tolerance and packaging specifications for your production line requirements.

Fixed Inductors Selection Notes

Select this component when high-frequency performance near 850 MHz is required in a through-hole format. The low DC resistance supports currents up to 2 A. Consider the physical size constraints of 2.41 mm diameter. Verify that the ±5% tolerance aligns with circuit precision needs compared to tighter tolerance alternatives.
