SMD1210-110-16V from TECHFUSE, 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 | One terminal pad of the non-polarized PPTC, in series with the load, rated 16 Vdc max, 1.10 A hold and 2.20 A trip at 25°C, 100 A max fault current. |
| 2 | 2 | passive | Second terminal pad of the non-polarized PPTC, tin-plated nickel-copper, interchangeable with the other pad, with 1.0 mm pads on a 2.0 mm gap per the recommended layout. |
