K1206L075 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 PPTC terminal pad (Tin-plated Nickel-Copper) in series with the protected line; rated 16 Vdc max, 0.75 A hold, 1.50 A trip, 35 A max fault current. |
| 2 | 2 | passive | Second non-polarized PPTC terminal pad, interchangeable with the other terminal; 0.090 ohm min to 0.500 ohm max (R1max) resistance before tripping at 25°C. |
