Jinrui Electronic Materials Co · Resettable Fuses · 1812
JK-mSMD030 from Jinrui Electronic Materials Co, 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 | Non-polarized PPTC terminal pad (tin-plated nickel-copper) in series with the protected line, rated 60 Vdc max, 0.30 A hold and 0.60 A trip at 25 °C. |
| 2 | 2 | passive | Second non-polarized PPTC terminal pad (tin-plated nickel-copper), interchangeable with pin 1, rated 40 A max fault current at 60 V with initial resistance 0.250 to 3.800 Ω. |

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