SMD1812-150

Shenzhen Jinkaisheng Elec · Resettable Fuses · 1812

SMD1812-150 from Shenzhen Jinkaisheng Elec, 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 Terminal 1 of the non-polarized resettable PTC fuse (tin-plated nickel-copper pad); JSMD1812-150 is rated 8 V max, 100 A Imax, 1.50 A hold, 3.00 A trip.
2 2 passive Terminal 2 of the non-polarized resettable PTC fuse (tin-plated nickel-copper pad); the device is symmetric, with 0.040 ohm min and 0.160 ohm max resistance (Ri min / R1max).

CAD (KiCad official)

  • Symbol: SMD1812-150
  • 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: smd1812-150-etched.step / smd1812-150-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812-150.step / smd1812-150.glb are the bare package body.
