RUILON Shenzhen Ruilongyuan Elec · NTC Thermistors · 0805

RL0805N104J3950H from RUILON Shenzhen Ruilongyuan Elec, in a 0805. 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 Terminal electrode of the two-terminal NTC thermistor. Passive, non-polarized; either terminal may be used as input or output. Nominal R25 = 100 kΩ ±5%, B25/50 = 3950 K ±3%.
2 2 passive Second terminal electrode of the two-terminal NTC thermistor. Passive, non-polarized. Max permissive operating current at 25°C referenced from Appendix A table.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rl0805n104j3950h.step 40 KB You want the bare part, or you mark your own boards.
rl0805n104j3950h-etched.step 3.0 MB You want the part with RL0805N104J3950H already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 721 faces against 26 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: RUILON Shenzhen Ruilongyuan Elec datasheet (10 pp, sha256 116c9fa4f00e855f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
