RLM25FEER005 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 5 mΩ (R005) metal-alloy current sense element, Ni/Sn plated, 2.0±0.2 mm terminal width (R≤3 mΩ) or 0.9±0.2 mm (R>3 mΩ); rated 2 W (E) with 1 mΩ to 50 mΩ range. |
| 2 | 2 | passive | Second terminal of the resistor, interchangeable with the first (non-polarized), at the opposite end of the 6.4±0.2 mm body; the pad drawing shows a separate Kelvin sensing trace at each terminal. |
