SDNT2012X224J4300HTF from Sunlord, in a 0805. 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	1	passive	Thermistor terminal 1. Non-polarized SMD terminal electrode; connect either terminal to the sensing circuit. Nominal 220 kΩ at 25°C with B25/50 = 4300 K.
2	2	passive	Thermistor terminal 2. Non-polarized SMD terminal electrode; connect either terminal to the sensing circuit. Nominal 220 kΩ at 25°C with B25/50 = 4300 K.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sdnt2012x224j4300htf.step`	40 KB	You want the bare part, or you mark your own boards.
`sdnt2012x224j4300htf-etched.step`	3.1 MB	You want the part with `SDNT2012X224J4300HTF` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 775 faces against 26 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.
