Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various corporate entities. Confirm RoHS compliance status directly with the supplier documentation, as historical data indicates variations across production batches. Ensure the package dimensions match the target footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 15 µH inductance is required in a compact SMD form factor. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the 135 mA current rating meets the operational demands of the specific circuit application.

Part Context

This part belongs to the Delevan 103R series of fixed RF inductors. These components are characterized by their small rectangular footprint and use of ferrite cores. The series provides standardized values for radio frequency circuits, offering a balance between size constraints and electrical performance for consumer and industrial electronics.

Replacement Considerations

The 103-153H shares identical electrical specifications including 15 µH inductance, 135 mA current rating, and 5.6 Ohm resistance. Verify physical package compatibility and tolerance levels before substitution.
