PRF18AS471QS5RB

Murata Electronics · PTC Thermistors · 0603

PRF18AS471QS5RB from Murata Electronics, in a 0603. 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 1 of the PTC thermistor. Symmetric, non-polar chip termination; connect in series with the load being thermally sensed.
2 2 passive Terminal 2 of the PTC thermistor. Symmetric, non-polar chip termination; interchangeable with pin 1.

  • PRF18AS471QS5RB

CAD (KiCad official)

  • Symbol: PRF18AS471QS5RB
  • Footprint: Resistor_SMD:R_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: prf18as471qs5rb-etched.step / prf18as471qs5rb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); prf18as471qs5rb.step / prf18as471qs5rb.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
prf18as471qs5rb.step 40 KB You want the bare part, or you mark your own boards.
prf18as471qs5rb-etched.step 2.6 MB You want the part with PRF18AS471QS5RB already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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: Murata Electronics datasheet (104 pp, sha256 4a6bb02a06805fc8, 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).
