**Milliohm** · Current Sense Resistors / Shunt Resistors · 1206

HoLLR1206-1W-50mR-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 resistor electrode (pure-tin plated end terminal) of the 1206 alloy resistor, rated 1W at 70℃ and 3.16A max rated current, with the Cu trace and sensing trace connected at this pad per the recommended solder pad drawing. |
| 2 | 2 | passive | Second resistor electrode (pure-tin plated end terminal) of the 1206 alloy resistor, rated 1W at 70℃ and 3.16A max rated current, with the Cu trace and sensing trace connected at this pad per the recommended solder pad drawing. |
