mt9102a.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 0 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

MT9102A

Magn Tek · Position Sensor · TO-92S

MT9102A from Magn Tek, in a TO-92S. 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 Vcc power_in Supply voltage input, 3.0-5.5 V operating (30 V absolute max). Typical supply current 6.7 mA @ Vcc=5V, 6.0 mA @ Vcc=3.3V. Decouple to GND close to the pin.
2 GND power_in Device ground reference. Return path for supply and output loading currents.
3 OUT output Ratiometric analog output. Quiescent voltage ≈ Vcc/2 (2.500 V @ Vcc=5V, 1.650 V @ Vcc=3.3V) with no magnetic field; swings 0.3-4.7 V @ Vcc=5V linearly with applied flux. Source/sink capability ±1.5 mA; output resistance ~2 Ω; supports up to 10 nF load capacitance.

CAD (KiCad official)

  • Symbol: MT9102A
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: mt9102a-etched.step / mt9102a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt9102a.step / mt9102a.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mt9102a.step 27 KB You want the bare part, or you mark your own boards.
mt9102a-etched.step 1.1 MB You want the part with MT9102A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 272 faces against 19 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: Magn Tek datasheet (12 pp, sha256 a002ba99c385ccb1, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
