• Axial through-hole termination style
• Iron-ferrite core material

Applications

• RF signal filtering
• High-frequency circuit assemblies
• General purpose inductive components

Procurement Notes

Verify the specific part number against official Gowanda Electronics documentation to confirm lead times and availability. Ensure compliance with RoHS requirements if applicable, as standard versions may contain lead. Confirm that the axial package dimensions and mounting requirements align with the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications. Consider the 435 mA current rating and 950 mΩ DC resistance limits. Verify that the 135 MHz self-resonant frequency meets the operational bandwidth needs. Ensure the physical size fits the assembly constraints.

Part Context

This component belongs to the Gowanda Electronics 15M series of wirewound, molded inductors. These parts are characterized by their axial leads and unshielded design, making them suitable for various electronic assemblies where shielding is not critical or where thermal dissipation is managed differently.

Replacement Considerations

Consult Gowanda Electronics for direct substitutes within the 15M series. Verify that any alternative maintains the 2.2 µH inductance, 435 mA current rating, and axial form factor to ensure mechanical and electrical compatibility.
