0501015.WR

Littelfuse · Disposable Fuses · 1206

0501015.WR from Littelfuse, 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 One fuse termination (Ag/Ni/Sn); the fuse is non-polarized, rated 20A at 32 V max (DC interrupting rating 150 A @ 32 VDC), with nominal resistance 0.00194 ohm.
2 2 passive Opposite fuse termination (Ag/Ni/Sn); the fuse is non-polarized and interchangeable with the other terminal, rated 20A at 32 V max.
