Fixed Inductors Procurement Notes

Verify the specific suffix 'H' against the manufacturer's datasheet to confirm mechanical or electrical variations compared to standard variants. Ensure compatibility with RoHS3 compliance requirements for your assembly process. Confirm that the non-standard package dimensions fit within your PCB footprint constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact 180 nH inductance is required alongside significant current capacity. The 37 A rating makes it suitable for bulk capacitors charging or VRM phases. Consider the unshielded nature if electromagnetic interference sensitivity is a primary concern, as magnetic fields may extend beyond the component body.
