Littelfuse · Resettable Fuses · 1812

1812L010DR from Littelfuse, 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 resettable PTC (solder-plated copper), rated 0.10 A hold, 0.30 A trip, 30 Vdc max and 100 A max fault current.
2 2 passive Second terminal of the non-polarized resettable PTC, in series with pin 1; resistance is 1.600 ohm min initial and 15.000 ohm max one hour after trip or reflow.

CAD (KiCad official)

  • Symbol: 1812L010DR
  • 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: 1812l010dr-etched.step / 1812l010dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1812l010dr.step / 1812l010dr.glb are the bare package body.
