LR20R003FE from HDK Hokuriku Elec Industry, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First electrode terminal of the 0.003 Ω ±1% current-sense element (copper electrode, Ni/Sn plated, 0.60±0.20 mm long), rated 0.5 W at up to 70 °C. |
| 2 | 2 | passive | Second electrode terminal of the 0.003 Ω current-sense element (copper electrode, Ni/Sn plated, 0.60±0.20 mm long); interchangeable with the other terminal, non-polarized. |
