K1812L010DR from KUU, in a 1812. 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 end terminal of the series PTC resettable fuse (non-polarized, interchangeable with the other terminal), rated 0.10 A hold current, 0.30 A trip current, 60 V max and 10 A max fault current. |
| 2 | 2 | passive | Other end terminal of the series PTC resettable fuse (non-polarized, interchangeable with the other terminal), rated 0.10 A hold current, 0.30 A trip current, 60 V max and 10 A max fault current. |
