Procurement Notes

Verify the specific manufacturer part number against official Gowanda Electronics documentation to confirm electrical parameters such as inductance, current rating, and tolerance. Ensure the unshielded axial package matches the target PCB layout requirements. Cross-reference datasheets for any updated RoHS compliance or material specifications prior to final procurement approval.

Selection Notes

Select this component when an unshielded axial inductor is required for commercial applications. The 3.3 µH value and 300 mA current rating define its operational limits. Consider the lack of shielding for potential electromagnetic interference sensitivity in the target circuit environment compared to shielded alternatives.
