Procurement Notes
Verify the specific suffix 'HS' against official Delevan documentation to confirm lead-free compliance and RoHS status. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm that the 260 mA rating meets the thermal requirements of the target PCB layout under worst-case ambient conditions.
Selection Notes
Select this component when an unshielded form factor is required to prevent magnetic coupling with nearby traces. The high-temperature rating supports operation in enclosed or high-heat electronic assemblies. Verify that the 1.4 Ohm DC resistance does not introduce excessive voltage drop in the specific circuit path.
Part Context
This part belongs to the Delevan 103R series of fixed RF inductors. These components are designed for surface-mount technology (SMT) integration into printed circuit boards. The series utilizes molded ferrite cores to provide stable inductance values across varying environmental conditions.
