SMD1812-200-16

hongjiacheng · Resettable Fuses · 1812

SMD1812-200-16 from hongjiacheng, 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 First terminal of the PTC device, rated Ihold 2.0A, Itrip 4.0A, Vmax 16V and Imax 40A.
2 2 passive Second terminal of the PTC device, in series with terminal 1, with the same ratings of Ihold 2.0A, Itrip 4.0A, Vmax 16V and Imax 40A.

CAD (KiCad official)

  • Symbol: SMD1812-200-16
  • 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: smd1812-200-16-etched.step / smd1812-200-16-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812-200-16.step / smd1812-200-16.glb are the bare package body.
