HoJLR2512-2W-38mR-1%-75ppm

Milliohm · Current Sense Resistors / Shunt Resistors · 2512

HoJLR2512-2W-38mR-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 2512 metal alloy plate resistor (2 W rated, 2mR to 500mR, ±75 ppm/°C, -50 to +170 °C), with a recommended solder pad of A=4.0 mm, L=4.1 mm and B=2.1 mm.
2 2 passive The other Ni/Sn-plated terminal of the 2512 metal alloy plate resistor, which is non-polarized and interchangeable with the first terminal, with the same recommended solder pad of A=4.0 mm, L=4.1 mm and B=2.1 mm.
