HoLLR1206-1W-70mR-1%

Milliohm · Current Sense Resistors / Shunt Resistors · 1206

HoLLR1206-1W-70mR-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 end electrode of the 1206 alloy current-sense resistor (the 70 mΩ, 1 W, ±1% part), carrying the current (A) and voltage-sense (V) contact points shown on the drawing; the datasheet gives a 2.95±0.25 mm resistance measurement span (A) between the two electrodes' sense points.
2 2 passive Second end electrode of the 1206 alloy current-sense resistor, carrying the current (A) and voltage-sense (V) contact points; the recommended pad uses a separate Cu trace for current and a sensing trace for voltage, with pad dimensions A 1.8±0.1, L 2.3±0.1, B 1.0±0.1 mm.
