Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan branding. Confirm RoHS compliance status directly with the supplier, as documentation varies between listings. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by the distributor. Cross-reference the datasheet to confirm the exact pinout and mechanical dimensions match your PCB layout constraints before finalizing the purchase order.

Fixed Inductors Selection Notes

Select this component when a high-inductance value (2.2 mH) with strict tolerance (1%) is required for RF applications. The unshielded design necessitates careful placement on the PCB to minimize electromagnetic interference with adjacent components. Verify that the operating current does not exceed the 120 mA rating to prevent saturation or thermal issues. Consider the physical axial footprint during the layout phase to ensure adequate clearance for the molded body.
