**TLC Electronic** · Disposable Fuses · 1206

F12F6 from TLC Electronic, 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-cap terminal of the F12F6 fuse, rated 6A with 32V/24V DC rating, 150A@32Vdc and 300A@24Vdc breaking capacity, and 16.5 mOhm typical cold resistance; the fuse is non-polarized. |
| 2 | 2 | passive | Other end-cap terminal of the F12F6 fuse, electrically interchangeable with the first terminal, with 142 mV typical voltage drop at rated current. |

## CAD (KiCad official)

- Symbol: `F12F6`
- Footprint: `Fuse:Fuse_1206_3216Metric`
- 3D model: 1206 (KiCad packages3D, STEP)
- 3D model files: `f12f6-etched.step` / `f12f6-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `f12f6.step` / `f12f6.glb` are the bare package body.
