SLSS49E-3

Slkor SLKORMICRO Elec · Hall Sensor · SOT-23

SLSS49E-3 from Slkor SLKORMICRO Elec, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply voltage input. Operating range 3 to 12 Vdc (absolute max 15 V, reverse -0.5 V). Typical supply current 5 mA at 5 Vdc.
2 GND power_in Ground return for the Hall element, bias, and output stage.
3 Vout output Ratiometric analog output proportional to the applied magnetic field. Quiescent output ~2.5 V (B=0) at VDD=5 V; ~1 V at -460 G, ~4 V at +460 G. Sensitivity ~3.25 mV/G at 5 V; output current up to 1.5 mA; recommended load ≥200 kΩ for

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: SLSS49E-3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: slss49e-3-etched.step / slss49e-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); slss49e-3.step / slss49e-3.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
slss49e-3.step 59 KB You want the bare part, or you mark your own boards.
slss49e-3-etched.step 1.8 MB You want the part with SLSS49E-3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 423 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Slkor SLKORMICRO Elec datasheet (9 pp, sha256 23154c5303ef8a2a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
