1812L050 from LUTE, 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 | First terminal of the non-polarized resettable PPTC (Ihold 0.50 A, Itrip 1.00 A at 25°C), soldered to a 1.78±0.1 mm x 3.15±0.1 mm pad; Vmax depends on the voltage suffix and Imax is 40 A. |
| 2 | 2 | passive | Second terminal of the non-polarized resettable PPTC (Ihold 0.50 A, Itrip 1.00 A at 25°C), soldered to a 1.78±0.1 mm x 3.15±0.1 mm pad, with pad pitch 3.45±0.1 mm. |
