SMD1812-075-33

hongjiacheng · Resettable Fuses · 1812

SMD1812-075-33 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 One terminal of the non-polarized PTC; the datasheet gives SMD1812-075-33 Ihold 0.75A, Itrip 1.5A, Vmax 33V, Imax 40A, with a 1.7±0.1 mm pad on a 3.0±0.1 mm gap.
2 2 passive The other terminal of the non-polarized PTC; the datasheet gives Ri min 0.09 ohm and R1 max 0.45 ohm, with a 1.7±0.1 mm pad by 3.5±0.1 mm.

CAD (KiCad official)

  • Symbol: SMD1812-075-33
  • 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: smd1812-075-33-etched.step / smd1812-075-33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812-075-33.step / smd1812-075-33.glb are the bare package body.

Provenance
