K1206L150AR

KUU · Resettable Fuses · 1206

K1206L150AR from KUU, 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 resettable PTC fuse; the K1206L150AR has a 1.50 A hold current, 3.00 A trip current, 6 V maximum voltage and 100 A maximum fault current.
2 2 passive Second terminal of the non-polarized resettable PTC fuse, interchangeable with the first; resistance is 0.030 Ω min to 0.170 Ω max.
