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). |
