FOJAN · Current Sense Resistors / Shunt Resistors · 2512
FRM252WJR010TN 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 terminal electrode of the 10 mΩ (R010) alloy current-sense resistor, rated 2 W at 70 °C and 63 A rated current (141 A max overload) for the 2512 type. |
| 2 | 2 | passive | Second terminal electrode of the 2512 resistor (interchangeable with the first); resistance is measured by Kelvin four-terminal sensing at the V/A points on the bottom of the electrodes. |
