TDK · NTC Thermistors · 0402

B57221V2103J060 from TDK, 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 Termination 1 of the two-terminal NTC thermistor. Non-polarized nickel-barrier SMD termination; resistance to termination 2 is 10 kΩ ±5% at 25 °C and decreases with temperature per R/T characteristic 8502 (B25/100 = 4000 K).
2 2 passive Termination 2 of the two-terminal NTC thermistor. Non-polarized nickel-barrier SMD termination; forms the second electrode of the multilayer NTC element with resistance 10 kΩ ±5% at 25 °C, max power 150 mW (on PCB).
