TA I Tech · Current Sense Resistors / Shunt Resistors · 1206

RLM12FTCMR039 from TA I Tech, 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 Terminal 1 passive One Ni/Sn-plated metal alloy terminal of the RLM12 1206 (3.2 x 1.6 mm) current sensing resistor, rated 1/4W, 1/2W or 1W by the power-rating code, with 0.6 ±0.20 mm thick terminal for 2mΩ to 50mΩ parts.
2 Terminal 2 passive The other Ni/Sn-plated metal alloy terminal of the RLM12 current sensing resistor, interchangeable with terminal 1 (non-polarised), with operating temperature -55℃ to +170℃.
