KNSMD012 from KUU, 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 | One terminal of the non-polarised PTC resettable fuse, interchangeable with the other terminal; rated Vmax 60 V, Imax 10 A, hold current 0.12 A and trip current 0.29 A at 25°C. |
| 2 | 2 | passive | Second terminal of the non-polarised PTC resettable fuse, interchangeable with the other terminal; rated Vmax 60 V, Imax 10 A, hold current 0.12 A and trip current 0.29 A at 25°C. |
