Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations across the product line. Ensure the axial lead configuration matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when high precision inductance is required for through-hole RF designs. The unshielded construction necessitates careful placement to avoid magnetic coupling with adjacent components. Verify that the 42.5 mA current limit aligns with the circuit's operational demands to prevent saturation or thermal issues.
