This type named as Resettable Fuse PPTC DIP JK600 Series is widely used,Central Office/telecom centers; Customer Premises Equipment; LAN/WAN equipment; Access equipment,etc
The resettable fuse is composed of specially treated polymer resin (Polymer) and conductive particles (Carbon Black) distributed inside. Under normal operation, the polymer resin tightly binds the conductive particles outside the crystalline structure to form a chain-shaped conductive electrical path. At this time, the recoverable fuse is in a low-resistance state (a), which is generated by the current flowing through the recoverable fuse on the line. The thermal energy is small and will not change the crystal structure. When the circuit is short-circuited or overloaded, the heat generated by the large current flowing through the recoverable fuse melts the polymer resin, rapidly growing in volume, forming a high-resistance state (b), and the operating current is rapidly reduced, thereby limiting and protecting the circuit.
By definition, PPTC (Polymer PositiveTemperature Coefficient) is called a resettable fuse, and ResettableFuse type fuses are resettable fuses.
When the fault is removed, the PTC can restore the fuse to re-cool and crystallize, the volume shrinks, the conductive particles form a conductive path again, and the fuse can be restored to a low resistance state.
