Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as distributor listings may vary between 330 µH and 270 µH specifications. Ensure the selected variant matches the required inductance value and tolerance for the target application design. Confirm RoHS compliance status prior to procurement.

Selection Notes

Select this component when an unshielded axial inductor with high self-resonant frequency is required for RF applications. Consider the low maximum DC current rating of 34 mA during circuit design. Verify that the physical dimensions fit the available PCB space and that the unshielded nature does not cause interference in dense layouts.
