BSMD1812L-600-12V

BHFUSE · Resettable Fuses · 1812

BSMD1812L-600-12V from BHFUSE, 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 at one end of the 1812 (4.5x3.2 mm) body, rated Vmax 12 Vdc, Imax 50 A, Ihold 6.00 A and Itrip 12.0 A at 25 °C, with a recommended pad of 1.78±0.1 mm by 3.15±0.1 mm.
2 2 passive Non-polarized PTC terminal at the opposite end of the body, interchangeable with the other terminal, with a pad pitch of 3.45±0.1 mm between pad edges and R1max 0.012 Ω after trip or reflow.

CAD (KiCad official)

  • Symbol: BSMD1812L-600-12V
  • 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: bsmd1812l-600-12v-etched.step / bsmd1812l-600-12v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsmd1812l-600-12v.step / bsmd1812l-600-12v.glb are the bare package body.
