**Fuzetec Tech** · Resettable Fuses · 1206

FSMD020-1206-R from Fuzetec Tech, 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 terminal of the non-polarized PTC resettable fuse (pure tin pad); the datasheet gives IH 0.20 A, IT 0.40 A, VMAX 30 VDC and IMAX 100 A for FSMD020-1206-R. |
| 2 | 2 | passive | Second terminal of the non-polarized PTC resettable fuse (pure tin pad); the datasheet gives RMIN 0.600 ohm and R1MAX 2.500 ohm for FSMD020-1206-R. |
