HoJLR1206-1W-33mR-1%

Milliohm · Current Sense Resistors / Shunt Resistors · 1206

HoJLR1206-1W-33mR-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 Ni/Sn-plated end terminal of the 33 mΩ ±1% alloy current-sense resistor (1 W rated power, TCR ±50 ppm/°C, -55 °C to +155 °C), interchangeable with the other terminal; a separate sensing trace is recommended on the pad.
2 2 passive Second Ni/Sn-plated end terminal of the 33 mΩ ±1% alloy current-sense resistor (1 W rated power, TCR ±50 ppm/°C, -55 °C to +155 °C), interchangeable with the other terminal; a separate sensing trace is recommended on the pad.
