Procurement Notes

Verify the specific suffix 'M' indicates ±20% tolerance against the manufacturer's latest datasheet. Confirm that the 1260 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the specified DC resistance and rated current limits during operation.

Selection Notes

Select this component when a precise 1 mH inductance value is required in a compact surface-mount form factor. Consider the series connection capability if higher inductance values are needed without increasing physical size. Evaluate the low rated current suitability for specific power levels before finalizing the design.
