YLR12-3-1F-W from Shenzhen Yezhan Elec, in a 2512. 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 Ni/Sn-plated Cu terminal of the 2-terminal 2512 current-sense resistor (YLR12, 3 W at 70°C, 1 mΩ per the -3-1 ordering code, F = ±1%), non-polarized. |
| 2 | 2 | passive | Second Ni/Sn-plated Cu terminal of the 2-terminal 2512 current-sense resistor (YLR12, 3 W at 70°C, operating temperature -65°C to 170°C), non-polarized. |
