TA I Tech · Current Sense Resistors / Shunt Resistors · 2512

RLM25JECR025 from TA I Tech, in a 2512. 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 terminal of the 25 mΩ (R025) metal-alloy current-sense element, Ni/Sn plated, 1W rated (C) at 70°C ambient, derated to 0 at 170°C.
2 2 passive Other terminal of the 25 mΩ (R025) metal-alloy current-sense element, Ni/Sn plated; rated current is I=√(P÷R) and the recommended pad layout for 4-50 mΩ is a=4.0, b=2.1, L=4.1 mm with sensing traces taken from the pads.
