Fixed Inductors Procurement Notes

Verify that the specific part number suffix matches the required electrical parameters, as variations exist within the series. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure storage conditions account for moisture sensitivity level 1 requirements to maintain component integrity during assembly processes.

Fixed Inductors Selection Notes

Select this component when an unshielded design is acceptable to minimize size while maintaining high current handling capabilities. The 1812 footprint offers a balance between power dissipation and board space efficiency. Consider the 33 MHz self-resonant frequency limit to ensure suitability for the target operating bandwidth without parasitic interference.
