K1206L050 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 | Non-polarized terminal of the resettable PPTC fuse (IH 0.50 A hold, IT 1.00 A trip at 25°C, Vmax 24 V, Imax 40 A), interchangeable with the other terminal. |
| 2 | 2 | passive | Non-polarized terminal of the resettable PPTC fuse (IH 0.50 A hold, IT 1.00 A trip at 25°C, Vmax 24 V, Imax 40 A), interchangeable with the other terminal. |
