Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure compatibility with target circuit requirements. Confirm that the unshielded configuration aligns with electromagnetic interference constraints. Check RoHS compliance status through authorized distributors or direct manufacturer channels prior to procurement. Ensure storage and handling procedures adhere to moisture sensitivity level guidelines for surface-mount components.

Fixed Inductors Selection Notes

Select this component when designing RF circuits requiring a 1.8 uH inductance with high current handling capabilities up to 900 mA. The unshielded wire-wound structure is appropriate for applications where magnetic field containment is not critical but high Q performance is desired. Consider the 225 MHz self-resonant frequency limit for signal integrity in higher frequency designs. Evaluate thermal management needs given the +105 C maximum operating temperature rating.
