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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Sunlord |+| Package | 0805 |+| Category | Sensor |+| Pins | 2 |++## Ordering variants++- `SDNT2012X473J3950HTF`+- `SDNT2012X473J3950HTFSDNT1608`+- `SDNT2012X473J3950HTFSDNT1005`+- `SDNT2012X473J3950HTFSDNT0603`++## CAD (KiCad official)++- Symbol: `SDNT2012X473J3950HTF`+- Footprint: `Resistor_SMD:R_0805_2012Metric`+- 3D model: 0805 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Sunlord datasheet](docs/sdnt2012x473j3950htf-datasheet.pdf) (4 pp, sha256 `8828a0b6b75af3a4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
