HoYLR1206-1W-40mR-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 | One terminal electrode of the 1206 alloy current-sense resistor (E=0.6±0.2 mm), 1W rated power, maximum operating voltage (P*R)^½. |
| 2 | 2 | passive | Second terminal electrode of the 1206 alloy current-sense resistor (E=0.6±0.2 mm), interchangeable with the other terminal as the part is non-polarized. |
