FEMTOSMDC010F-2 from Littelfuse, in a 0603. 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 tin-plated terminal of the non-polarized PTC device, rated 12.0 VDC maximum with 40 A short circuit current, 0.10 A hold and 0.25 A trip at 25°C. |
| 2 | 2 | passive | Second tin-plated terminal of the non-polarized PTC device, interchangeable with the other terminal, with 1.70 to 8.00 ohms resistance at 25°C. |
