mt9103et.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 -> 3 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

MT9103ET

Magn Tek · Position Sensor · SOT-23

MT9103ET from Magn Tek, 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	Vcc	power_in	Supply voltage input, 3.0V to 5.5V operating range (absolute max 30V). Typical supply current 6.7 mA @ Vcc=5V. Bypass with 100 nF to GND close to the pin.
2	Out	output	Ratiometric rail-to-rail analog output proportional to the perpendicular magnetic flux density. Quiescent voltage Vcc/2 (2.500V @ Vcc=5V, 1.650V @ Vcc=3.3V). Source/sink capability ±1.5 mA; output resistance ~2 Ω. Recommended output loading: RL ≥ 4.7 kΩ to GND or Vcc, and CL ≤ 10 nF (typ 4.7 nF).
3	GND	power_in	Ground / reference return for supply and output.

Symbol: MT9103ET
Footprint: Package_TO_SOT_SMD:SOT-23
3D model: SOT-23 (KiCad packages3D, STEP)
3D model files: mt9103et-etched.step / mt9103et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt9103et.step / mt9103et.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mt9103et.step`	59 KB	You want the bare part, or you mark your own boards.
`mt9103et-etched.step`	1.4 MB	You want the part with `MT9103ET` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 345 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.
