HoJLR2512-2W-90mR-1%-75ppm 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 Ni/Sn-plated terminal of the 90 mΩ metal-alloy current-sense resistor (2 W rated, solder pad A=4.0, L=4.1, B=2.1 mm recommended). |
| 2 | 2 | passive | Other Ni/Sn-plated terminal of the 90 mΩ metal-alloy current-sense resistor, interchangeable with the first (non-polarized, 2 W rated at 70°C, operating -50°C to +170°C). |
