HoLLR1206-1W-47mR-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 of the HoLLR1206 4-terminal-style current-sense resistor, with current (A) and voltage-sense (V) measurement points on the pad; series rating 1/2W-1W, 31.6 A maximum rated current, 70.7 A maximum overload current. |
| 2 | 2 | passive | Second resistor electrode, mirror of the first, with its own current (A) and voltage-sense (V) measurement points; series operating range -55 to +170 °C, power derated above 70 °C. |
