RXEF185
by Littelfuse(美国力特)
The Littelfuse RXEF185 belongs to the polymeric resettable fuse family used for overcurrent protection. These devices increase resistance when tripped and can return to a low-resistance state after the fault is removed and the device cools. This through-hole part is represented by a 2-pin schematic symbol and the FUSE-TH_L17.4-W3.1-P5.10-D1.2-S3.1 footprint with 2 pads. Both are provided in the free KiCad download, along with a 3D model to help review placement around nearby components. This conversion has been used in real designs by 2 ProtoFlow engineers. Open the RXEF185 files directly in ProtoFlow to incorporate the fuse into a design.
