SMD1812P300SLR

PTTC Polytronics Tech · Resettable Fuses · 1812

SMD1812P300SLR from PTTC Polytronics Tech, 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 solder-plated copper terminal of the PPTC; Ihold 3.00 A, Itrip 6.00 A, Vmax 24 Vdc, Imax 50 A, Rmin 0.001 ohm, R1max 0.030 ohm.
2 2 passive Non-polarized solder-plated copper terminal of the PPTC; Ihold 3.00 A, Itrip 6.00 A, Vmax 24 Vdc, Imax 50 A, Rmin 0.001 ohm, R1max 0.030 ohm.

CAD (KiCad official)

  • Symbol: SMD1812P300SLR
  • 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: smd1812p300slr-etched.step / smd1812p300slr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812p300slr.step / smd1812p300slr.glb are the bare package body.
