NCP21XW223J03RA

Murata Electronics · NTC Thermistors · 0805

NCP21XW223J03RA from Murata Electronics, 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 Thermistor terminal 1 (Ag + Ni + Sn plated electrode). Non-polarized - interchangeable with terminal 2. Resistance between terminals is nominally 22kΩ at 25°C with a negative temperature coefficient (B25/50 = 3950K).
2 2 passive Thermistor terminal 2 (Ag + Ni + Sn plated electrode). Non-polarized - interchangeable with terminal 1. Resistance between terminals is nominally 22kΩ at 25°C with a negative temperature coefficient (B25/50 = 3950K).

Provenance

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

  • Datasheet: Murata Electronics datasheet (None pp, sha256 fa902261686a4ce8, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
