CMFA303J3950HANT from FH Guangdong Fenghua Advanced Tech, in a 0603. 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 | T1 | passive | Terminal 1 of the NTC thermistor. Non-polar: resistance between terminals 1 and 2 is 30 kΩ ±5% at 25 °C and decreases with rising temperature per the B=3950 K characteristic. |
| 2 | T2 | passive | Terminal 2 of the NTC thermistor. Non-polar: resistance between terminals 1 and 2 is 30 kΩ ±5% at 25 °C and decreases with rising temperature per the B=3950 K characteristic. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 657 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.
