Fixed Inductors Procurement Notes

Verify component authenticity against official manufacturer documentation. Confirm that the part number matches the specific 1025R series designation. Ensure the supplier provides valid traceability records. Check for compliance with relevant environmental standards if required by the application. Validate physical dimensions against the datasheet specifications before integration.

Fixed Inductors Selection Notes

Select this component when a 10 µH inductance value is required with a 144 mA current capacity. The 3.3 Ohm DC resistance must be compatible with the circuit's power loss constraints. The unshielded nature requires consideration of magnetic interference in dense layouts. Verify that the axial package fits the available PCB footprint and mounting orientation.
