SMD1210-150-12 from hongjiacheng, 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 | Non-polarized PTC terminal; device holds 1.50 A (Ihold) and trips at 3.00 A (Itrip) at 25°C, rated 12 V max at 40 A max fault current. |
| 2 | 2 | passive | Non-polarized PTC terminal; interchangeable with the other terminal, mounted on 1.2±0.1 mm x 1.9±0.1 mm pads at 1.9±0.1 mm spacing. |
