SMD1210-020 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, 1.0±0.1 mm pad width in the recommended layout); the device is rated 30 Vdc max and 100 A max fault current, with Ihold 0.20 A and Itrip 0.40 A at 25°C. |
| 2 | 2 | passive | Non-polarized PPTC terminal (tin-plated nickel-copper pad, 1.0±0.1 mm pad width in the recommended layout); the device is rated 30 Vdc max and 100 A max fault current, with Ihold 0.20 A and Itrip 0.40 A at 25°C. |
