NCP21XW223J03RA from Murata Electronics, 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 (Ag + Ni + Sn plated electrode). Non-polarized - interchangeable with terminal 2. Resistance between terminals is nominally 22kΩ at 25°C with a negative temperature coefficient (B25/50 = 3950K). |
