FRM252WJR100TN from FOJAN, 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 | First end terminal (Cu/Ni/Sn plated electrode) of the 2512 alloy current-sense resistor, rated 2 W at 70 °C with 500 V DC dielectric withstanding voltage; Kelvin four-terminal sensing points sit on the bottom of this electrode. |
| 2 | 2 | passive | Second end terminal (Cu/Ni/Sn plated electrode) of the 2512 alloy current-sense resistor, rated 2 W at 70 °C with 500 V DC dielectric withstanding voltage; Kelvin four-terminal sensing points sit on the bottom of this electrode. |
