Procurement Notes

Verify the specific tolerance suffix 'JS' against official manufacturer documentation to confirm the 5% tolerance specification. Ensure the ordering part number matches the exact series designation. Confirm RoHS compliance status directly from the datasheet before procurement. Cross-reference the Mouser part number 807-103R-270JS for accurate sourcing details.

Selection Notes

Select this component for RF designs requiring 27 nH inductance with tight 5% tolerance. Consider the 925 mA current rating and 114 mOhm DCR for power handling needs. Verify that the 1.625 GHz self-resonant frequency aligns with the target operating range. Ensure the 103/R package dimensions fit the PCB layout constraints.

Part Context
