SMD1210-110-24V 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 | Non-polarized PPTC terminal (tin-plated nickel-copper pad); device is rated 24 Vdc max, 100 A max fault current, 1.10 A hold and 2.20 A trip current at 25°C. |
| 2 | 2 | passive | Non-polarized PPTC terminal (tin-plated nickel-copper pad); interchangeable with the other terminal, in series with the protected load, with resistance 0.050 Ω min to 0.210 Ω max before tripping. |
