Self-resetting fuses, fuses, PPTC,resettable fuse,POLY-Fuse

During the use of the self-resetting fuse, when the circuit is short-circuited or overloaded, the temperature rise is increased by the high current of the fuse. When the Curie temperature is reached, the density of the state rapidly decreases, the phase change increases, and the internal conductivity links are avalanche or broken, and the fuse is moved step-by-step to a high-impedance state, the current is quickly pinched off, thereby quickly and accurately limiting and protecting the circuit. Its tiny current keeps the fuse in a protected state. After the power is turned off and the fault is eliminated, the temperature is reduced, the density of states is increased, and the phase transition is recovered, the nanocrystals are reduced into a chain-like conductive path, and the self-resetting fuse is returned to its normal state without manual replacement.
