Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm the exact tolerance and electrical characteristics, as variations exist within the 1537R series. Confirm RoHS compliance status and REACH registration details directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a high-inductance value (200 µH) is required in an unshielded axial package. Ensure the 120 mA current rating meets the circuit's operational needs and that the physical dimensions fit the PCB layout constraints.

Part Context

This part belongs to the Delevan 1537R series of molded RF inductors. These components are designed for through-hole mounting and offer reliable performance in radio frequency environments. The series provides various inductance values with different tolerance options.

Replacement Considerations

Check for direct substitutes within the 1537R series from API Delevan. Verify equivalent inductance, tolerance, and current ratings if considering alternative manufacturers.
