# HoLR2512-2W-8mR-1%-15ppm

**Milliohm** · Current Sense Resistors / Shunt Resistors · 2512

HoLR2512-2W-8mR-1%-15ppm from Milliohm, in a 2512. 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 of the two terminals of the HoLR2512 metal-alloy resistor, which the datasheet lists as a 2-terminal type rated 1W to 3W with a resistance range of 0.5 mΩ to 300 mΩ. The datasheet states no polarity, so the resistor is treated as non-polar. |
| 2 | 2 | passive | The other of the two terminals of the HoLR2512 metal-alloy resistor, which the datasheet lists as a 2-terminal type with a TCR of 15 to 50 ppm/°C and an operating range of -55 °C to +170 °C. The datasheet states no polarity, so the resistor is treated as non-polar. |
