FRM121WFR010TM from FOJAN, in a 1206. 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 resistor terminal (Sn-plated electrode) of the 1206 alloy current-sense resistor; the 1 W part is rated 31 A continuous and 70 A max overload, with resistance measured by Kelvin four-terminal sensing at the bottom of the product. |
| 2 | 2 | passive | Second resistor terminal (Sn-plated electrode) of the 1206 alloy current-sense resistor; the 1 W part is rated 31 A continuous and 70 A max overload, with resistance measured by Kelvin four-terminal sensing at the bottom of the product. |
