STE1206M1W0R005FS

Walter Elec · Current Sense Resistors / Shunt Resistors · 1206

STE1206M1W0R005FS from Walter Elec, 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 One of the two end terminals (Sn/Ni/Cu electrode, side electrode) of the 5 mΩ 1 W current sense resistor, electrically interchangeable with the other terminal; resistance is measured by the 4-wire method.
2 2 passive Second end terminal of the two-terminal 1206 current sense resistor (STE1206M1W0 series, 1.0 W at 70 °C ambient, operating range -55 to 155 °C), interchangeable with the other terminal.
