HoLR0805-1 from Milliohm, in a 0805. 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 end terminals of the 0805 chip current-sense resistor (terminal count 2); the 0805 rated power is 1/2W or 3/4W with maximum rated current 15.8A or 19.36A, and the resistor is non-polarized. |
| 2 | 2 | passive | The other end terminal of the 0805 chip current-sense resistor (terminal count 2); the 0805 rated power is 1/2W or 3/4W with maximum overload current 31.6A or 38.72A, and the resistor is non-polarized. |
