Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact electrical tolerances and material specifications. Ensure the procurement channel provides valid traceability records for the established reliability series. Confirm RoHS compliance status as required by the end application regulations before finalizing orders.

Selection Notes

Select this component when a high-inductance value is required in a compact axial package. The unshielded construction necessitates careful PCB layout to minimize electromagnetic interference coupling with adjacent traces. Verify that the 123 mA current rating aligns with the peak operational demands of the target circuit to prevent saturation or thermal issues.

Part Context

This part belongs to the 1537R series of RF inductors manufactured by API Delevan. The series is characterized by molded, unshielded coils designed for reliable performance in radio frequency environments.
