HoJLR1206-1W-35mR-1% from Milliohm, in a 1206. 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 end terminal of the 35 mΩ metal alloy current-sense resistor, rated 1 W (0.75 W/1 W series) and -55°C to +155°C operating temperature. |
| 2 | 2 | passive | Second Ni/Sn-plated end terminal of the resistor, interchangeable with the first (non-inductive, non-polarized), with a recommended 4.7 mm pad span L and 1.8 mm pad width A on page 3. |
