SDNT2012X473J3950HTF

Sunlord · NTC Thermistors · 0805

SDNT2012X473J3950HTF 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-polar SMD end cap; connects to one side of the NTC element. Resistance to pin 2 is 47 kΩ ±5% at 25 °C, decreasing with rising temperature per the B=3950 K characteristic.
2 2 passive Thermistor terminal 2. Non-polar SMD end cap; interchangeable with pin 1. Keep sense current below Imax = 0.2 mA to avoid self-heating error.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sdnt2012x473j3950htf.step 40 KB You want the bare part, or you mark your own boards.
sdnt2012x473j3950htf-etched.step 3.2 MB You want the part with SDNT2012X473J3950HTF already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 777 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.

Provenance

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

  • Datasheet: Sunlord datasheet (4 pp, sha256 8828a0b6b75af3a4, 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).
