Cross-check results
  • Schematic symbol: Correct for a 2-terminal passive inductor.
  • Pin/terminal count: Correct — datasheet shows a 2-terminal inductor.
  • Pin descriptions: Electrically acceptable as passive terminals, but the datasheet marks the start of winding with a dot; the schematic terminals do not explicitly describe start/end of winding.
  • Footprint: Matches the datasheet land pattern in the important dimensions: two rectangular SMT pads, approx. 1.8 mm × 5.7 mm, with 2.8 mm pad gap / 4.6 mm pad center spacing.
  • Mismatch flagged: The footprint includes a pin-1/start-winding silkscreen dot, but the schematic terminal mapping is effectively reversed visually: schematic pin 1 is on the left, while footprint pad 1 is at positive X/right in the KiCad footprint. Electrically this usually does not matter for an inductor, but it is worth aligning if the start-of-winding mark is intended to be meaningful.
