HoYH1206-1W-5mR-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 end terminal (Sn/Ni/Cu electrode) of the 1206 chip resistor, 5 mΩ ±1%, 1 W rated at 70°C, TCR ±100 ppm, non-polarized so interchangeable with the other terminal. |
| 2 | 2 | passive | Second end terminal (Sn/Ni/Cu electrode) of the 1206 chip resistor, 5 mΩ ±1%, 1 W rated at 70°C, TCR ±100 ppm, non-polarized so interchangeable with the other terminal. |
