cjiang Changjiang Microelectronics Tech · NTC Thermistors · 0402

FNTC0402X104F3950FB from cjiang Changjiang Microelectronics Tech, in a 0402. 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 First terminal electrode (Ag+Ni+Sn end cap). Thermistors are non-polarized, so pins 1 and 2 are interchangeable.
2 2 passive Second terminal electrode (Ag+Ni+Sn end cap). Thermistors are non-polarized, so pins 1 and 2 are interchangeable.
