1812L050

LUTE · Resettable Fuses · 1812

1812L050 from LUTE, in a 1812. 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 First terminal of the non-polarized resettable PPTC (Ihold 0.50 A, Itrip 1.00 A at 25°C), soldered to a 1.78±0.1 mm x 3.15±0.1 mm pad; Vmax depends on the voltage suffix and Imax is 40 A.
2 2 passive Second terminal of the non-polarized resettable PPTC (Ihold 0.50 A, Itrip 1.00 A at 25°C), soldered to a 1.78±0.1 mm x 3.15±0.1 mm pad, with pad pitch 3.45±0.1 mm.

  • 3D model: 1812 (KiCad packages3D, STEP)
  • 3D model files: 1812l050-etched.step / 1812l050-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1812l050.step / 1812l050.glb are the bare package body.

Provenance

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

  • Datasheet: LUTE datasheet (10 pp, sha256 7648b4ad1356cb36, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
