HoLR2512-3W-2mR-1%

Milliohm · Current Sense Resistors / Shunt Resistors · 2512

HoLR2512-3W-2mR-1% 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 First Ni/Sn-plated end terminal of the non-inductive 2512 alloy current-sense resistor (6.4x3.2 mm body); the part is non-polar, rated 3W for 1mΩ to 100mΩ, operating -50°C to +170°C.
2 2 passive Second Ni/Sn-plated end terminal of the resistor, interchangeable with the first; the recommended 2 mΩ footprint (1~4 mR) uses pad A=4.0, L=1.3, B=3.1 mm, with a separate sensing trace per pad.
