nSMD200 from TECHFUSE, in a 1206. 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 end termination of the non-polarized PPTC (tin-plated nickel-copper); nSMD200 is rated Ihold 2.00 A, Itrip 3.50 A, Vmax 6.0 Vdc, Imax 100 A. |
| 2 | 2 | passive | Opposite end termination of the non-polarized PPTC, soldered to a 1.0 mm by 1.9 mm pad per the recommended layout, with 2.0 mm pad spacing as dimensioned. |
