CMFA222J3450HANT from FH Guangdong Fenghua Advanced Tech, in a 0603. 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 (Ag with Ni/Sn plating) at one end of the chip NTC thermistor body; R25 is 2.2 kΩ ±5% (J) and B25/50 is 3450 K, and the thermistor is non-polarized. |
| 2 | 2 | passive | Terminal electrode (Ag with Ni/Sn plating) at the opposite end of the chip NTC thermistor body; operating temperature range is -40℃ to +125℃, and the thermistor is non-polarized. |
