SL1210210 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 of the non-polarized resettable PTC; SL1210210 holds 2.10 A and trips at 4.2 A at 25°C, with Vmax 6.0 V and Imax 50 A. |
| 2 | 2 | passive | Other terminal of the non-polarized resettable PTC; resistance is 0.005 Ω min to 0.010 Ω max initially and 0.030 Ω max (R1max) after reflow. |
