Bourns · Current-sense resistor (metal strip) · 2512 (6332 metric)
Bourns CSS2H-2512R-L300F: a 0.3 mOhm, ±1 %, 6 W EB-welded metal-strip current-sense resistor in the 2512 case, low inductance, AEC-Q200 compliant.
Note: The footprint is KiCad's generic R_2512_6332Metric (the land pattern the AM32 ESC board uses). It has not been compared pad by pad with the recommended pad layout on Bourns' datasheet p.2: check that before a new board relies on it. The 3D model is KiCad's generic 2512 resistor body, not the metal-strip shape.
Verification
A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.
