Procurement Notes

Verify the specific tolerance suffix (K) against project requirements to ensure the correct inductance variance is selected. Confirm that the 47 mA current rating meets the operational load needs. Ensure the axial lead dimensions are compatible with the target PCB layout and hole spacing. Check for any specific environmental certifications required by the end application.

Selection Notes

Select this component when an unshielded axial inductor with a powdered iron core is required for RF or general-purpose filtering. Consider the 270 µH value and 25 Ohm DCR limits for circuit impedance matching. Evaluate the 47 mA current capacity against peak load conditions. Verify that the -55 °C to 105 °C operating range aligns with the system's thermal environment.
