K1812L260

KUU · Resettable Fuses · 1812

K1812L260 from KUU, 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 First terminal of the non-polarized PTC resettable fuse (2.60 A hold, 5.20 A trip at 25°C, 16 V max, 100 A max fault current), soldered to one 1.5 mm pad.
2 2 passive Second terminal of the non-polarized PTC resettable fuse (2.60 A hold, 5.20 A trip at 25°C, 16 V max, 100 A max fault current), soldered to the other 1.5 mm pad.

CAD (KiCad official)

  • Symbol: K1812L260
  • 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: k1812l260-etched.step / k1812l260-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); k1812l260.step / k1812l260.glb are the bare package body.
