Fixed Inductors Procurement Notes

Verify the specific electrical parameters against the official Abracon datasheet prior to integration, as manufacturing specifications may be subject to revision. Confirm that the package dimensions and thermal characteristics align with the target printed circuit board layout constraints. Ensure compliance with relevant regional environmental regulations such as RoHS requirements for the final assembly process.

Fixed Inductors Selection Notes

Select this component when a low-profile, shielded inductor is required for high-current applications. The 120 µH value suits filtering needs in communication and portable electronics. Consider the 178 mA current rating to ensure adequate headroom for the specific circuit load. The shielded type reduces noise coupling compared to unshielded alternatives in dense assemblies.
