**Bel Fuse** · Resettable Fuses · 1812

0ZCG0075FF2C from Bel Fuse, in a 1812. 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 (matte tin-plated copper pad); the 0ZCG0075FF2C is rated 0.75 A hold, 1.50 A trip, 16 Vdc max and 100 A max fault current. |
| 2 | 2 | passive | Other terminal of the non-polarized PTC (matte tin-plated copper pad); resistance is 0.110 ohm min and 0.450 ohm max (R1max) at 23 °C. |

## CAD (KiCad official)

- Symbol: `0ZCG0075FF2C`
- Footprint: `Fuse:Fuse_1812_4532Metric`
- 3D model: 1812, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal _1806_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `0zcg0075ff2c-etched.step` / `0zcg0075ff2c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `0zcg0075ff2c.step` / `0zcg0075ff2c.glb` are the bare package body.
