RXEF300
by Littelfuse(美国力特)Resettable overcurrent protection is the role of the Littelfuse RXEF300, listed in the source record as fuseRXEF300. This polymer PTC fuse increases its resistance during an overcurrent condition and can recover after the fault is removed and the device cools. Typical applications include protection of power inputs and individual circuit branches. The conversion is backed by use in real designs by 2 ProtoFlow engineers. Its free KiCad files contain a 2-pin symbol, the 2-pad FUSE-TH_L24.0-W3.0-P10.40-D1.2-S3.0 through-hole footprint, and a 3D model for assembly review. The RXEF300 can be opened directly in ProtoFlow.
