JK-mSMD020

Jinrui Electronic Materials Co · Resettable Fuses · 1812

JK-mSMD020 from Jinrui Electronic Materials Co, 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 tin-plated nickel-copper terminal pad of the PTC fuse; JK-mSMD020 is rated 30 Vdc max, 0.20 A hold and 0.40 A trip at 25°C.
2 2 passive Second non-polarized tin-plated nickel-copper terminal pad, interchangeable with the first; JK-mSMD020 is rated Imax 100 A and has R1max of 5.000 ohm.

CAD (KiCad official)

  • Symbol: JK-mSMD020
  • 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: jk-msmd020-etched.step / jk-msmd020-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jk-msmd020.step / jk-msmd020.glb are the bare package body.
