FMF25FPKR015-LH 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 metal termination of the 2512 (6.20±0.20 x 3.25±0.20 mm) metal-strip current-sense resistor, with the resistive alloy element between it and the other termination (termination length a = 0.80±0.20 mm). |
| 2 | Terminal 2 | passive | Second metal termination of the 2512 metal-strip current-sense resistor; the part is non-polarized, so either end may serve as the sense terminal (max working voltage per rating table for 2512 is 316mV at 1W or 447mV at 2W). |
