1206L300

LUTE · Resettable Fuses · 1206

1206L300 from LUTE, 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 First terminal of the non-polarized PPTC; the 1206L300/6NR and /12NR parts are rated 3.00 A hold and 6.00 A trip at 25°C, 6 V or 12 Vdc max respectively.
2 2 passive Second terminal of the non-polarized PPTC (interchangeable with pin 1); 100 A max fault current, R1max 0.050 Ω after trip or reflow.
