K1206L150AR 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 | First terminal of the non-polarized resettable PTC fuse; the K1206L150AR has a 1.50 A hold current, 3.00 A trip current, 6 V maximum voltage and 100 A maximum fault current. |
| 2 | 2 | passive | Second terminal of the non-polarized resettable PTC fuse, interchangeable with the first; resistance is 0.030 Ω min to 0.170 Ω max. |
