1206L300SL12AR from LUTE, 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 | First terminal of the non-polarized PPTC resettable fuse, rated 3.00 A hold, 6.00 A trip, 12.0 Vdc max, 35 A max fault current, 0.003-0.030 Ω resistance. |
| 2 | 2 | passive | Second terminal of the non-polarized PPTC resettable fuse, interchangeable with the first, with a 3.00 A hold current at 25℃ and 12.0 Vdc maximum voltage. |
