Procurement Notes

Verify the specific ordering suffix against official API Delevan documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required inductance value and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when high inductance stability is required for RF applications. The ±1% tolerance ensures precise circuit tuning compared to standard variants. Consider the 130 mA current limit and 6.05 Ohm resistance for power handling requirements. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent components.

Part Context

This component belongs to the 1537/R series of established reliability RF inductors manufactured by API Delevan.
