Describe：Self-restoring fuse (PPTC). It is used to protect the circuit from damage caused by excessive current. When a circuit overcurrent fault occurs, it will rapidly switch from a low-resistance state to an extremely high-resistance state, thereby limiting the current; after the fault is eliminated and the power is cut off, it can automatically reset and return to the low-resistance state, achieving maintenance-free circuit protection.
