Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and reliability class. Confirm RoHS compliance status as historical data indicates non-compliance for certain variants. Ensure the ordering part number matches the required inductance value and current rating specifications before procurement.

Selection Notes

Select this component when a high-inductance value is required in a compact axial form factor. The 130 µH rating suits lower frequency RF applications compared to other members of the 1537/R series. Verify that the 137 mA current limit meets the circuit requirements and that the unshielded nature does not interfere with nearby sensitive components.

Part Context

This part belongs to the Delevan 1537/R series of RF inductors. These components are characterized by their molded epoxy construction and axial leads. The series offers various inductance values tailored for radio frequency applications, providing established reliability for demanding electronic environments.

Replacement Considerations

Cross-reference with ER1537-82JR for equivalent electrical specifications. Verify physical dimensions and lead spacing compatibility during substitution.
