Resettable fuse, also known as polymer positive temperature thermistor PTC, is a polymer and conductive particles and the like. After special processing, the conductive particles in the polymer chain constituting the conductive path. When the normal operating current through (or components in a normal ambient temperature) when, PTC resettable fuse low resistance state; when the circuit has abnormal over current through (or ambient temperature), the large current  T8 Tube (or ambient temperature) the heat generated by the rapid expansion of the polymer, the conductive particles will cut off a conductive path, PTC resettable fuse high-impedance state; when the circuit overcurrent (over-temperature condition) disappears, the polymer was cooled, the volume is restored normal, wherein the conductive particles form conductive path again, PTC   LED Flexi  resettable fuse and was initial resistance state. In the normal operating state of self-recovery fuse fever small, abnormal working conditions in its high resistance to heat large, also limits the current through it, and thus play a protective role. In the specific circuit, you can select:
