0805L150SLYR

Littelfuse · Resettable Fuses · 0805

0805L150SLYR from Littelfuse, in a 0805. 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 Terminal of the non-polarized PPTC (0805L150SL: Ihold 1.50 A, Itrip 3.00 A, Vmax 6 Vdc, Imax 50 A); the two terminals are interchangeable.
2 2 passive Second terminal of the non-polarized PPTC (0805L150SL: Ihold 1.50 A, Itrip 3.00 A, Vmax 6 Vdc, Imax 50 A); the two terminals are interchangeable.
