NTCG203NH103JT1 from TDK, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Terminal electrode of the non-polarized NTC thermistor (10 kΩ at 25°C, ±5%, 0.44 mA permissible operating current); interchangeable with the other terminal, with a recommended land width of 0.7 to 0.9 mm. |
| 2 | 2 | passive | Second terminal electrode of the non-polarized NTC thermistor (operating range -40 to 125°C, maximum rated power 200 mW at 25°C); the two lands are 0.9 to 1.2 mm apart. |
