HoLLR2010-1.5W-25mR-1% from Milliohm, in a 2010. 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 terminal of the two-terminal 2010 alloy current-sense resistor (1.5 W rated at 70°C ambient, max rated current 38.73 A, max overload current 86.6 A, 4-wire resistance measurement on the electrode). |
| 2 | 2 | passive | Second terminal of the two-terminal 2010 alloy current-sense resistor (1.5 W rated, TCR ±50 ppm/°C, operating range -55 to +170°C), with the sensing trace taken from the inner side of the pad. |
