SMD1812P010TF

RUILON Shenzhen Ruilongyuan Elec · Resettable Fuses · 1812

SMD1812P010TF from RUILON Shenzhen Ruilongyuan 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 One terminal of the non-polarized resettable PTC fuse (Ihold 0.1 A, Itrip 0.3 A, Vmax 30 VDC, Imax 0.5 A), a 4.37-4.73 mm x 3.07-3.41 mm body soldered to a 1.78 mm pad.
2 2 passive The other terminal of the non-polarized resettable PTC fuse (Ihold 0.1 A, Itrip 0.3 A, Vmax 30 VDC, Imax 0.5 A), interchangeable with the first terminal.

CAD (KiCad official)

  • Symbol: SMD1812P010TF
  • 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: smd1812p010tf-etched.step / smd1812p010tf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smd1812p010tf.step / smd1812p010tf.glb are the bare package body.
