Procurement Notes
Verify the active status of this component as some distributors list it as obsolete. Confirm lead availability through authorized channels. Ensure the unshielded package type matches your PCB layout requirements. Check RoHS compliance details if required by your manufacturing standards. Validate the specific pinout against your schematic before procurement.
Selection Notes
Choose this part for applications requiring a 470 nH value with low DC resistance. The unshielded design may require careful placement to minimize EMI. Consider the 555 mA current limit for power handling. Compare with shielded alternatives like the 105R-471H if magnetic interference is a concern. Ensure the non-standard footprint fits your board design.
Part Context
