Procurement Notes

Verify the specific suffix 'G' against official API Delevan documentation to confirm exact tolerance and material specifications. Ensure compatibility with RoHS requirements if mandated by the end application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and standard packaging quantities before procurement.

Selection Notes

Select this component for applications requiring high precision (2% tolerance) in RF signal processing. The unshielded nature requires careful layout consideration to prevent magnetic interference with adjacent components. Verify that the 137 mA current rating meets the circuit's operational demands and that the physical size fits the designated PCB footprint.

Part Context

This part belongs to the 1537/R series of fixed RF inductors manufactured by API Delevan. These components are designed for through-hole mounting and are characterized by their molded epoxy encapsulation.
