K1210L200 from KUU, in a 1210. 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 terminal of the two-terminal PPTC resettable fuse, rated IH 2.00 A hold and IT 4.00 A trip at 25℃, Vmax 8 V, Imax 40 A. |
| 2 | 2 | passive | Second terminal of the two-terminal PPTC resettable fuse, interchangeable with the first (non-polarized), rated IH 2.00 A hold and IT 4.00 A trip at 25℃, Vmax 8 V, Imax 40 A. |
