HoYLR1206-1W-50mR-1%

Milliohm · Current Sense Resistors / Shunt Resistors · 1206

HoYLR1206-1W-50mR-1% from Milliohm, in a 1206. 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 terminal of the 50 mΩ ±1% 1 W alloy current-sense resistor (non-polarized, interchangeable with pin 2); the resistive element lies between the two terminals.
2 2 passive Second terminal of the 50 mΩ ±1% 1 W alloy current-sense resistor (non-polarized, interchangeable with pin 1); rated 1W, max 4.47A, -55°C to +170°C.
