SMD1812-200-30

hongjiacheng · Resettable Fuses · 1812

SMD1812-200-30 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 Non-polarized PTC terminal on one end of the 4.5x3.2mm 1812 body; device is rated Vmax 30V, Imax 40A, Ihold 2A, Itrip 4A, and may be fitted either way round.
2 2 passive Non-polarized PTC terminal on the opposite end of the body; the two terminals are interchangeable, with R1max 0.1 ohm after trip or reflow and an operating range of -40C to +85C.

CAD (KiCad official)

  • Symbol: SMD1812-200-30
  • 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: smd1812-200-30-etched.step / smd1812-200-30-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812-200-30.step / smd1812-200-30.glb are the bare package body.
