FMF25JPKR0L5XBH from PSA Prosperity Dielectrics, 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 | Terminal 1 | passive | One end termination of the 0.5 mΩ metal-strip sensing element (2512, 3W, 70°C), non-polarized and interchangeable with the other terminal; 2512 0.5-3 mΩ recommended pad W 4.00 mm, D 3.00 mm, L 7.30 mm. |
| 2 | Terminal 2 | passive | Other end termination of the sensing element, non-polarized; at 0.5 mΩ the datasheet gives max working current 77.5 A and max overload current 173.2 A (operating range -55 to +170°C). |
