China Radial Lead PPTC Resettable Fuse, Find details about China Lead Fuse, PPTC Fuse from Radial Lead PPTC Resettable Fuse
LB050LVF is a polymer resettable fuse .At a high temperature and high voltage condition, the fuse is made through a special technology after it adopts high-molecular organic polymer and conductive particle material. The fuse can reset itself and can be used repeatedly after it blows for some reasons. The performance will not decay despite the constantly repeated times. The fuse can reset for more than a thousand times and thus to a large extent, the cost is saved. In the circuit, the fuse can be used as a thermal fuse. Therefore, to some extent, it shows the performance of thermal fuse in circuit and makes the role of thermal fuse.
