Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm exact electrical tolerances and physical dimensions. Ensure compatibility with existing PCB footprints and soldering processes. Confirm RoHS compliance status and packaging quantities directly with authorized distributors or the manufacturer prior to ordering.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in an unshielded axial form factor. The 100 µH rating and 400 mA current handling make it suitable for specific RF stages where shielding is not critical. Verify that the 16 MHz self-resonant frequency aligns with the target operational bandwidth of the application circuit.

Fixed Inductors Part Context

This component belongs to the 4470R series of molded RF inductors manufactured by API Delevan. The series offers various inductance values in a consistent axial package style.
