Procurement Notes

Verify the specific suffix requirements for your application, as Gowanda offers variants such as the LF (lead-free) version. Confirm that the unshielded nature aligns with your EMI constraints. Ensure the 65 mA current rating meets your circuit demands. Check RoHS compliance status if required by your procurement policy. Validate the axial lead dimensions against your board layout specifications before ordering.

Selection Notes

Select this component when a high-inductance value is needed in a compact axial package. The powdered iron core provides distinct performance characteristics compared to ferrite cores. Consider the unshielded design implications for nearby sensitive components. Evaluate the 18.8 Ω DC resistance impact on your circuit efficiency. Ensure the operating temperature range covers your environmental conditions.
