Procurement Notes

Verify the exact suffix designation when ordering, as variants such as 15M303JLF exist. Confirm that the unshielded construction aligns with system EMC requirements. Ensure the 83 mA current limit meets the operational load demands. Check RoHS compliance status if required by project specifications. Validate the axial package dimensions against the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a 300 µH inductance value is required at high frequencies near 790 kHz. The iron powder core offers distinct characteristics compared to ferrite alternatives. Consider the unshielded nature for applications where external magnetic interference is manageable. The axial form factor dictates the board space allocation. Evaluate the 11.5 Ω DCR impact on circuit efficiency and thermal dissipation under continuous load conditions.
