# TLC-MSMD030

**TLC Electronic** · Resettable Fuses · 1812

TLC-MSMD030 from TLC Electronic, 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 |
|---|---|---|---|

## CAD (KiCad official)

- Symbol: `TLC-MSMD030`
- 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: `tlc-msmd030-etched.step` / `tlc-msmd030-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlc-msmd030.step` / `tlc-msmd030.glb` are the bare package body.
