Fixed Inductors Procurement Notes
Verify the exact suffix designation during procurement, as variations such as LF or K may indicate different material compositions or compliance standards. Confirm that the nonstandard package dimensions align with the target PCB footprint to ensure proper mechanical fit and assembly compatibility.
Fixed Inductors Selection Notes
Select this component when an unshielded form factor is required to minimize magnetic interference with adjacent sensitive traces. Ensure the 395 mA current rating meets the operational load requirements and that the 2.3 Ohm DC resistance does not introduce excessive voltage drop in the application circuit.
Fixed Inductors Part Context
This part belongs to the SMRF series of molded inductors manufactured by Gowanda Electronics. The series typically includes various inductance values and shielding options, catering to diverse industrial and commercial electronic applications requiring reliable passive components.
Fixed Inductors Replacement Considerations
Direct substitutes include the SMRF5025-391KLF variant, which shares identical electrical specifications but may differ in lead-free compliance status. Verify dimensional compatibility before replacing with other unshielded molded inductors from different manufacturers.
