JK-nSMD175 from Jinrui Electronic Materials Co, in a 1206. 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 | Non-polarized tin-plated nickel-copper terminal pad on one end of the 1206 PPTC; rated 6.0 Vdc max, Ihold 1.75 A and Itrip 3.30 A at 25 °C, Imax 100 A. |
| 2 | 2 | passive | Non-polarized tin-plated nickel-copper terminal pad on the opposite end of the 1206 PPTC; in series with pin 1 (resistance 0.020 to 0.115 Ω), operating -40 °C to 85 °C. |
